How can I handle in my activity layout long text from which I don´t know how long it is?
I have this text in a textview and when it is too long, it overlays my button.
Are you talking about a Textview or Button? If its a Textview ,You can use a marque textview like below.It will scroll automatically so that all the text will be shown
<TextView
android:id="#+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:ellipsize="marquee"
android:lines="1"
android:fadingEdge="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:text="Your Looooooooooooooooooooooooooooooooooooooooong text!"
android:textColor="#000"
android:textSize="15dp" />
and in your code,
textview.setSelected(true);
textview.setEllipsize(TruncateAt.MARQUEE);
textview.setHorizontallyScrolling(true);
textview.setSingleLine(true);
textview.setLines(1);
If you want an expandable Textview, do something like this.It have a button to expand/collapse textview.
In xml,
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="sdfsdfsdfsfasfdsfgdfgdfsgsdfgsdfgsdfgsdgsdgdsgdsgsdfgdsgdsfgsdfgsdgsdfgsdfgdsfgsdgdsgfsdgfsdgsdfgdsgdsfgdsfgdsfgsdghjghjghjghjghjfg"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/relativeLayout1"
android:text="Button" />
</RelativeLayout>
and in code,
boolean checkflag = true;// declare it as public
final RelativeLayout rl=(RelativeLayout)findViewById(R.id.relativeLayout1);
Button b=(Button)findViewById(R.id.button1);
final TextView text=(TextView)findViewById(R.id.textView1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(checkflag==true)
{
text.setSingleLine(true);
checkflag=false;
}
else
{
text.setSingleLine(false);
checkflag=true;
}
}
});

If i am adding multiple text views in android it gets hide i need to break when screen finished
As an example my code is something like this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/layout5"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is the text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="last checking text"/>
</LinearLayout>
and the result seems to be
I need the text to break down when screen finished down
and break to another line.
this is only the example code i am doing this thing programmatically, so please dont answer of adding more linear layout.
For flexible layout you can go with FlexboxLayout and details you can get from Android Developers Blog and for Open source FlexboxLayout dependency you can reach to Github.
If you want your textView appearing with multiple line with a scrollable properties, then no need to use multiple textView.
Check the bellow solution:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"`enter code here`
android:background="#000000"
android:orientation="vertical" >
<TextView
android:id="#+id/textView_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#40000000"
android:maxLines="100"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:scrollbarThumbVertical="#android:color/transparent"
android:scrollbars="vertical"
android:textColor="#color/white"
android:textSize="16sp"
android:textStyle="bold" />
</LinearLayout>
And bellow code on your Activity:
TextView txtView = (TextView) findViewById(R.id.TextView_id);
txtView.setText("your text here");
txtView.setMovementMethod(new ScrollingMovementMethod());
If You want to create TextView programmatically and make Listener for each .
Here is the Code . First remove all textview in layout.
TextView tv[] = new TextView[subCategory.length];
for (int i = 0; i < subCategory.length; i++) {
tv[i] = new TextView(this);
tv[i].setText(subCategory[i]);
tv[i].setId(i);
layout5.addView(tv[i]);
tv[i].setOnClickListener(onclicklistener);
}
And For Listner
OnClickListener onclicklistener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v == tv[0]){
//do whatever you want....
}
}
};
If you want to use number of textviews at run time, You can try using GridView as
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>
And Gridview item as TextView
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text"
/>
You can perform action in onItemClickListener() //based on the position or textview text, choose action using switch case or something else.
GridView gridView = (GridView) findViewById(R.id.grid_view);
gridView.setAdapter(yourCustomAdapterObject);
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//here view is your textview
switch (position) {
case 0: //action
break;
case 1://action
break;
....
}
}
});
this below code for my login_activity xml:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView

android:layout_marginTop="20dp"
android:layout_marginRight="50dp"
android:layout_marginLeft="50dp"
android:textColor="#fff"
android:layout_gravity="center_horizontal"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/colorPrimaryDark"
android:text="#string/need_an_account"
android:layout_marginTop="20dp"
android:textStyle="italic"
android:layout_gravity="center_horizontal"
android:id="#+id/need_an_account" />
</LinearLayout>
</ScrollView>
I want to click on TextView id=need_an_account that like below:
public class LoginActivity extends Activity implements View.OnClickListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_login);
}
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.need_an_account:
// some code
break;
}
}
}
Note that i don't want to use findViewById() method
But onClick not Working at all how can I solve this problem?
If you don't want to use OnClickListener, Here is an alternative -
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/colorPrimaryDark"
android:text="#string/need_an_account"
android:layout_marginTop="20dp"
android:textStyle="italic"
android:onClick="myTextViewMethod"
android:layout_gravity="center_horizontal"
android:id="#+id/need_an_account" />
Now write myTextViewMethodin you Activity
public void myTextViewMethod(View v) {
// Do your stuff here...
}
Plus point, No need to implement OnClickListener, Android will do it in background.
And if you wanna use an Interface View.OnClickListener
Simple, set need_an_account.setOnClickListener(this);
In oncreate add this,
TextView need_an_account = (TextView) findViewById(R.id.need_an_account);
need_an_account.setOnClickListener(this);
You can add OnClick to your xml to avoid using findViewById:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/colorPrimaryDark"
android:text="#string/need_an_account"
android:layout_marginTop="20dp"
android:clickable="true"
android:textStyle="italic"
android:onClick="textViewClick"
android:layout_gravity="center_horizontal"
android:id="#+id/need_an_account" />
and then write your function in the activity as:
public void textViewClick(View v) {
switch (v.getId())
{
case R.id.need_an_account:
// some code
break;
}
}
no need to implement an OnClickListener if you dont want to define the TextView programatically. Remember to set TextView to clickable and for authenticity i also set background to ?selectableItemBackground so the user knows that the TextView can be clicked
I have a Relative layout as:
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
I want my relative layout to perform onCLickListener but does not work.
I am able to do the setonclicklistener but it works only with the textview part and not for the image.
btniPay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//for ipay
}
});
This works for the text part only but not for the image. Any idea what I might be missing.
Alternatively, you can add android:clickable="false" in your button xml attribute.
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:clickable="false"
android:textColor="#ffffff" />
</RelativeLayout>
may be you can find some good example thats use with imageview and buttons but the easy way i did it by using adding TextView instead of images and buttons.
<RelativeLayout
android:id="#+id/layout1"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:clickable="true"
android:gravity="right">
<TextView
android:id="#+id/englishheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/urduheading1"
android:text="English text"
android:textColor="#ffffff"
android:textSize="15sp" />
<TextView
android:id="#+id/urduheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="15dp"
android:text="urdu text1"
android:textColor="#ffffff"
android:textSize="16sp" />
<View
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_alignParentBottom="true"
android:layout_marginTop="8dp"
android:background="#ffffff" />
</RelativeLayout>
Here is java code to perform onClick.
RelativeLayout layout1 = (RelativeLayout) view.findViewById(R.id.layout1);
layout1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something
}
});
see my code easily run change your code:
.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:id="#+id/btn"
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/ic_launcher"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
</RelativeLayout>
.java file
public class MainActivity extends Activity {
TextView tv;
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView) findViewById(R.id.tv);
btn = (Button) findViewById(R.id.btn);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "text", Toast.LENGTH_SHORT).show();
}
});
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "button", Toast.LENGTH_SHORT).show();
}
});
}
}
Just mark android:clickable="true" in your RelativeLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_id"
android:clickable="true">
Using ButterKnife lib make bind here:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_xml_name);
ButterKnife.bind(this);
}
#OnClick(R.id.activity_id)
void onActivityClick() {
// do smth ...
}
I am new to Android so I've been trying to tweak around for the past couple days but am stuck at this part. For my app, I'm trying to input a Button "Add More" which inflates a view to help incorporate user input but I'm running into issues. I looked around and I used his source code to help with my issue but I am running into the problem that my inflated xml layout is overlapping my previous set-up layout.
This is the layout that I have setup for my new_class_container file
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
This is how the layout for the code above looks like and I want to be able to press the "Add More" Button and it inflates to "create a new row", per say, of the TextViews of Assignment Type and Grade Weight and EditTexts of the respective TextViews. But when I run the app and press add more, the new set of TextView + EditText pop up right on top of what I have rather than underneath. The following is my other xml file new_class
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/register_assign_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assignment_type"
android:textAppearance="?android:attr/textAppearanceMedium"/>
<TextView
android:id="#+id/register_weight_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assign_percent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_marginLeft="30dp"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText

android:layout_marginLeft="30dp"
android:gravity="center_horizontal"
android:inputType="number"
android:singleLine="true">
</EditText>
</LinearLayout>
</LinearLayout>
And this is the Java Code that I have
public class NewClass extends Activity{
private RelativeLayout mContainerView;
private Button mAddButton;
private View mExclusiveEmptyView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_class_container);
mContainerView = (RelativeLayout) findViewById(R.id.parentView);
mAddButton = (Button) findViewById(R.id.btnAddNewItem);
}
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
//TODO: Handle Screen Rotation
}
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// TODO: Handle screen rotation:
// restore the saved items and inflate each one with inflateEditRow;
}
// onClick handler for the "Add new" button;
public void onAddNewClicked(View v) {
// Inflate a new row and hide the button self.
inflateEditRow(null);
v.setVisibility(View.GONE);
}
// onClick handler for the "X" button of each row
public void onDeleteClicked(View v) {
// remove the row by calling the getParent on button
mContainerView.removeView((View) v.getParent());
}
private void inflateEditRow(String name) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.new_class, null);
//final ImageButton deleteButton = (ImageButton) rowView
// .findViewById(R.id.buttonDelete);
final EditText editText = (EditText) rowView
.findViewById(R.id.register_assign_edit);
if (name != null && !name.isEmpty()) {
editText.setText(name);
} else {
mExclusiveEmptyView = rowView;
//deleteButton.setVisibility(View.INVISIBLE);
}
// A TextWatcher to control the visibility of the "Add new" button and
// handle the exclusive empty view.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
if (s.toString().isEmpty()) {
mAddButton.setVisibility(View.GONE);
//deleteButton.setVisibility(View.INVISIBLE);
if (mExclusiveEmptyView != null
&& mExclusiveEmptyView != rowView) {
mContainerView.removeView(mExclusiveEmptyView);
}
mExclusiveEmptyView = rowView;
} else {
if (mExclusiveEmptyView == rowView) {
mExclusiveEmptyView = null;
}
mAddButton.setVisibility(View.VISIBLE);
// deleteButton.setVisibility(View.VISIBLE);
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
});
// Inflate at the end of all rows but before the "Add new" button
mContainerView.addView(rowView, mContainerView.getChildCount() - 1);
}
}
What can I do to prevent it from overlapping and showing up underneath? And how will I be able to move the button each time it's 'updated'? Because if I move the button to the new_class xml file then it won't show up originally for me to add more views.
I tried implementing the following code and what it did was enabled me to properly get a dynamic view added the first time but each time after it was overlapping the added view.
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, R.id.register_assign_edit);
rowView.setLayoutParams(p);
This will work with having two layout files: main_layout and layout_to_include.
main_layout.xml

To use these layouts in your code:
....
setContentView(R.layout.main_layout);
....
llAddingContainer = (LinearLayout) findViewById(R.id.llAddingContainer);
// Clicking on this button will add another view from 'layout_to_include' to the ScrollView
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
View view = getLayoutInflater().inflate(R.layout.layout_to_include, null);
// Find the elements in this view and set them up
EditText et1 = (EditText) view.findViewById(R.id.editText1)
....
....
....
// Add the view to the LinearLayout inside ScrollView
llAddingContainer.addView(view);
});
I'm not sure, but you can try follow code to move any view. I recommend to use RelativeLayout like your main layout.
RelativeLayout.LayoutParams bParams1 = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
bParams1.leftMargin = (int) leftMrgn;
bParams1.topMargin = (int) topMgrn;
bParams1.height = (int) bHeight;
bParams1.width = (int) bWidth;
anyView.setLayoutParams(bParams1);
RelativeLayouts act like a FrameLayout if you don't give them any LayoutParams (constraints like below, above, center, etc.).
You can either construct the appropriate RelativeLayout.LayoutParams, or better yet, create an empty vertical LinearLayout in your first layout that will contain the rows. Then, just add the rows to the LinearLayout instead of the RelativeLayout.
i am confusing how to play gif image in my layout. my layout using RelativeLayout and the image is at center. i've looking the way to play the gif but the example is not tell me how to implement it to my layout that contains another widget there not only to play the gif alone. please help me to do this.
here is the code:
choosepet_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<ImageView
android:id="#+id/petpic"
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<RelativeLayout
android:layout_width="fill_parent"

</RadioGroup>>
<TextView

android:layout_toRightOf="#+id/genderGroup"
android:layout_alignParentBottom="true"
android:layout_marginBottom="38px"

</RelativeLayout>
</LinearLayout>
and this is the choosepet.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.choosepet_layout);
Spinner spinnerPet = (Spinner) findViewById(R.id.pet);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.pet_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerPet.setAdapter(adapter);
EditText nameField = (EditText) findViewById(R.id.name);
nameField.requestFocus();
ImageButton processButton = (ImageButton) findViewById(R.id.process);
processButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), petMain.class);
startActivityForResult(myIntent, 0);
}
});
final ImageView imgPet = (ImageView) findViewById(R.id.petpic);
spinnerPet.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?>parent,
View view, int pos, long id){
String petType = parent.getItemAtPosition(pos).toString();
if(petType.equals("Anjing")){
imgPet.setImageResource(R.drawable.dog);
}else{
imgPet.setImageResource(R.drawable.cat);
}
}
#Override
public void onNothingSelected(AdapterView parent) {
// TODO Auto-generated method stub
}
});
}
thank you in advance!
as far as i know android does not support gif animation you have to create the animation by other ways like series of images
like in example linked below
http://yekmer.posterous.com/how-to-make-a-loading-animator-in-android
Android can decode gif format.
take a look at this post.
