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"?>

<EditText

</RelativeLayout>
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/register_assign_edit"

android:layout_marginTop="22dp"
android:gravity="center_horizontal"

<EditText
android:id="#+id/register_weight_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

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:id="#+id/register_assign_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:hint="#string/example_assign"
android:singleLine="true">
</EditText>
<EditText
android:id="#+id/register_weight_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="#string/example_weight"
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.

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.

The EditText is Dynamically added by user .
how get data from each dynamically created EditText .or get values from the dynamically created EditTexts when the user tap a save button, then store all of them , dynamically added by user and save as Share preferences or save as array thanks guys

You could retrieve the value by looping the parentView, something like this
ArrayList getEditTextList()
{
ArrayList<String> list = new ArrayList<String>();
int size = parentLinearLayout.getChildCount()
for (int i=0 ; i < size ; i++)
{
View view = parentLinearLayout.getChildAt(i);
EditText text = view.findViewById(R.id.yourEditTextName);
list.add(text.getText().toString());
}
return list;
}
Later you can add the values to Shared preference either by converting Arraylist to Json String or Adding it one by one.
Have a relative layout with some views (textviews, edittext and button). When viewing and hiding the textview, the layout not moving up. While hiding the view (textview.setVisibility(View.INVISIBLE)) it create blank space instead of pushing the view up.

Before Enabling view
After enabling and disabling the view
View.GONE This view is invisible, and it doesn't take any space for layout purposes.
View.INVISIBLE This view is invisible, but it still takes up space for layout purposes.
btn_disable.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
textView.setVisibility(View.GONE);
}
});
Setting the visibility of any view to View.INVISIBLE just hides the view. The view is not shown but it takes up the space required by it.
You should set the visibility to View.GONE if you do not want it to take any space also.
Official documentation state the following:
View.INVISIBLE
This view is invisible, but it still takes up space for layout
purposes. Use with setVisibility(int) and android:visibility.
View.GONE
This view is invisible, and it doesn't take any space for layout
purposes. Use with setVisibility(int) and android:visibility.
I have been reading about how to dynamically add an EditText field to my Linear Layout, every-time a user clicks a TextView (which has an onClick Listener attached).
I have had some mild success - I know that the EditText field is being created because when the button is clicked, all other elements move up as if something is being added to the screen.
My problem is that the EditText aren't visible and I haven't a clue why that is, so any help would be appreciated.
The the app isn't crashing so nothing to add in terms of the StackTrace and Log, as far as the app is concerned, everything is being created.

I have a layout in which I have an image,textview, editbox and a button so whenever the keyboard opens I wanted my screen to scroll down to the button so that the user can always type and press submit button. I did do this by using scrollview but than I removed the scroll view did some changes and now when I again use a scrollview it does not work.
here is the code please check.
layout_file:

and in my main activity I am using the scrollto method to go to my image button.
public class MainActivity extends AppCompatActivity {
ImageButton submit;
EditText feedBack;
static public String saveFeedBack="";
ScrollView view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
submit = (ImageButton) findViewById(R.id.submit);
feedBack = (EditText) findViewById(R.id.feedback);
view = (ScrollView) findViewById(R.id.scroll);
view.scrollTo(submit.getScrollX(),submit.getScrollY());
}
public void onSubmit(View view){
saveFeedBack = feedBack.getText().toString();
if(saveFeedBack.length() >=4) {
Intent intent = new Intent(this, Main3Activity.class);
startActivity(intent);
}
else{
Toast.makeText(getApplicationContext(),"Enter valid Feedback please.",Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onRestart() {
super.onRestart();
feedBack.setText("");
feedBack.setHint("Enter Feedback");
}
}
but when I run my application the scrollview scrolls to my edit text but not my button. I have tried adjustResize,adjustPan and all those things but none of them worked.
ok after much of research I have solved your problem. Actually the thing is when you use scroll to any position inside onCreate it doesn't work because a small delay is required to inflate the view.
So use the below code inside your onCreate:
view.postDelayed(new Runnable() {
#Override
public void run() {
view.fullScroll(ScrollView.FOCUS_DOWN);
}
},200);
Hope it Helps!!!
In a layout I have a button which toggles view's visibility (hides/displays a linear layout). Inside this layout I also have a spinner. When I click the button it toggles the visibility but it does not change the layout height to wrap_content, but when I change the spinner value it updates the height.
This is the XML Layout code
<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"

Here is the activity code where I toggle the views visibility
//Set the on item selected listener on the parameter spinner for alarm1 condition 1
spnParameterA1C1.setOnItemSelectedListener(new OnItemSelectedListener()
{
#Override
public void onItemSelected(AdapterView<?> parent, View view,int position, long id)
{
tvUnitA1C1.setText(unitList.get(position));
}
#Override
public void onNothingSelected(AdapterView<?> parent){}
});
//Set onClickListener for add condition button for Alarm 1
btnAddA1C1.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
layoutA1C2.getLayoutParams().height = LayoutParams.WRAP_CONTENT;
layoutA1C2.setVisibility(android.view.View.VISIBLE);
btnAddA1C1.setVisibility(android.view.View.INVISIBLE);
layoutA1.getLayoutParams().height = LayoutParams.WRAP_CONTENT;
}
});
//Set onClickListener for add condition button for Alarm 1
btnRemoveA1C2.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
layoutA1C2.getLayoutParams().height = 0;
btnAddA1C1.setVisibility(android.view.View.VISIBLE);
layoutA1C2.setVisibility(android.view.View.INVISIBLE);
layoutA1.getLayoutParams().height = LayoutParams.WRAP_CONTENT;
}
});
I have also tried layoutA1.refreshDrawableState();. Can anybody tell me which method should I call to refresh the layout length?
You need to set the layout params again in order to refresh the view.
try :
LayoutParams params = layoutA1C2.getLayoutParams();
params.height = LayoutParams.WRAP_CONTENT;
layoutA1C2.setLayoutParams(params); // this call is what you need to add
