MainActivity
show = (TextView)findViewById(R.id.getdirection);
show1 = (TextView)findViewById(R.id.hide);
rt = (RelativeLayout)findViewById(R.id.rl_ListView2);
show.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(rt.getVisibility()==View.INVISIBLE)
{
rt.setVisibility(View.VISIBLE);
}
show.setVisibility(View.INVISIBLE);
}
});
show1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(rt.getVisibility()==View.VISIBLE)
{
rt.setVisibility(View.INVISIBLE);
}
show1.setVisibility(View.INVISIBLE);
}
});
Try this:
You are getting layout1 in half screen from starting due to weight property. You can try not giving weight in starting and give it programatically on button click.
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
button1.setVisibility(View.GONE); //hide old button
layout2.setVisibility(View.VISIBLE); //show layout2
//set Relativelayout 1 to half screen
RelativaLayout.LayoutParams params = layout1.getLayoutParams();
params.weight = 0.5;
layout1.setLayoutParams(params);
}
});
Hope this helps.
Set visibility as Gone instead of Invisible
button.setOnClickListener(this);
public void onClick(View v) {
layoutid.setVisibility(View.GONE);
}
You can try with isShown() as suggested by Amiya
<b>
button2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
if(button1.isShown()) {
// Your_Staff
}
else{
// Your_Staff
}
}
});
</b>
From my view you did not set the orientation in the LinearLayout to be vertical for the two RelativeLayouts. I also suggests you put the map and Button in a FrameLayout as well instead of RelativeLayout.

I allow the App's User to change the ImageButton's pictures from the drawable folders?
It's possible?
I want associate this action after onLongClickListener,
I put in the Drawable folder about 3 or 4 pictures(png) and the User can choose one for its ImageButton.
Yes, you can. On onLongClickListener click, you can pop up the option and then put a switch statement and put the following for each of the cases:
aButton.setImageResource(R.drawable.image2);
Here is the more detailed answer:
Put the following at the bottom of the layout (just before the last closing layout tag)
<FrameLayout
android:id="#+id/imagebuttonselectorlayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
android:background="#android:color/black" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageButton
android:id="#+id/imgButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image1" />
<ImageButton
android:id="#+id/imgButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image2" />
</LinearLayout>
</FrameLayout>
Then, in the java class file, add the following lines:
FrameLayout mFrameLayout;
ImageButton mImageButton1;
ImageButton mImageButton2;
mFrameLayout = (FrameLayout)findViewById(R.id.imagebuttonselectorlayout);
mImageButton1 = (ImageButton)findViewById(R.id.imgButton1);
mImageButton2 = (ImageButton)findViewById(R.id.imgButton2);
For the onLongClick of the main image button
mImageButton1.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
mFrameLayout.setVisibility(View.VISIBLE);
return true;
}
});
Add the following lines in the same file to complete the functionality:
mImageButton1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mainImageButton.setImageResource(R.drawable.image1);
mFrameLayout.setVisibility(View.GONE);
}
});
mImageButton2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mainImageButton.setImageResource(R.drawable.image2);
mFrameLayout.setVisibility(View.GONE);
}
});
I have a activity in that I need to change the layout.
In the first layout I have four buttons to display and in the second I need a GridView to display images.
I need to show the second layout in an AsyncTask onPostExecute method.
For now, I'm trying to set two setContentViews, but I get the following exception: ClassCastException
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_focusarea);
videoBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
animateBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
pdfBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadPDFFiles().execute();
}
});
}
And in my postExecute i try like this
protected void onPostExecute(String file_url) {
pDialog.dismiss();
runOnUiThread(new Runnable() {
public void run() {
setContentView(R.layout.gallery);
girGridView=(GridView) findViewById(R.id.gridView1_bir);
girGridView.setAdapter(new ImageAdapter(this));
girGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long arg3) {
Toast.makeText(getApplicationContext(), GridViewConfig.getResim_list().get(position), Toast.LENGTH_SHORT).show();
}
});
}
});
Instead of using two layouts use a single layout as bellow
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/MyLayoutOne"
android:layout_width="fill_parent"
android:visibility="gone"
android:layout_height="fill_parent" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Hi This is my first layout" />
<!-- Your first layout contents add here-->
</LinearLayout>
<LinearLayout
android:id="#+id/MyLayoutTwo"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Hi This is my Second layout" />
<!-- Your second layout contents add here -->
</LinearLayout>
</LinearLayout>
Add your first layout contents inside MyLayoutOne and second layout contents inside MyLayoutTwo
And use following codes inside your activity,
public class MainActivity extends Activity {
LinearLayout MyLayoutOne;
LinearLayout MyLayoutTwo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyLayoutOne=(LinearLayout)findViewById(R.id.MyLayoutOne);
MyLayoutTwo=(LinearLayout)findViewById(R.id.MyLayoutTwo);
// this will make first layout visible
MyLayoutOne.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
MyLayoutTwo.setVisibility(View.GONE);
//=========================================
//in your post create add this codes
//=========================================
// this will make first layout hidden
MyLayoutOne.setVisibility(View.GONE);
// this will make second layout visible in your layout
MyLayoutTwo.setVisibility(View.VISIBLE);
//=========================================
}
}
This is a simplest method you must study fragments for better UI management. You can use viewflipper also.
So Study Fragments and Viewflipper..
Instead of that you can have a layout that contains both a wrapper for your four buttons and other for the GridView while this last one is with visibility set to 'gone'.
When the AsycTask finished, you hide the buttons layout and show the GridView layout.
Why don't you set one content view with two layouts or two fragments? A layout can be like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text1">
</Button>
<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text2">
</Button>
<Button
android:id="#+id/button3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text3">
</Button>
<Button
android:id="#+id/button4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text4">
</Button>
<GridView
android:layout_width="match_parent"
android:layout_height="wrap_content"
...
</GridView>
</LinearLayout>
Use one setContentView() and define separates Linear/Relative layout one for buttons and second for gridView.And hide/show the Views according to your need.
onPostExecute of AsyncTask runs on UI thread so you need not specify runonUiThread explicitly.Instead of using 2 setcontent View it is better to have 2 views in your layout file and make it visible invisible as required.
Friend change the id of wrapper1 to child as below,
<LinearLayout 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=".Focusarea" >
<LinearLayout
android:id="#+id/wrapper1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:visibility="gone" >
<GridView
android:id="#+id/gridView1_bir"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center" >
</GridView>
</LinearLayout>
<RelativeLayout
android:id="#+id/wrapper2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/vid_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="18dp"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
</LinearLayout>
and initialize your linear layouts outside oncreate as below,
LinearLayout wrapper1;
RelativeLayout wrapper2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
wrapper1 = (LinearLayout)findViewById(R.id.wrapper1);
wrapper2=(RelativeLayout)findViewById(R.id.wrapper2);
// this will make first layout visible
wrapper2.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
wrapper1.setVisibility(View.GONE);
ImageView videoBtn = (ImageView) findViewById(R.id.vid_btn);
ImageView animateBtn = (ImageView) findViewById(R.id.anit_btn);
ImageView pdfBtn = (ImageView) findViewById(R.id.pdf_btn);
videoBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
animateBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
pdfBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadPDFFiles().execute();
}
});
}
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting VIDEOS
pDialog.dismiss();
vid=new ArrayList<String>(new ArrayList<String>(vid));
videoUrl=parsing.parse(videoUrl);
System.out.println("VIDEO URL" +videoUrl);
runOnUiThread(new Runnable() {
public void run() {
//--here you wont need to initialize again--
// this will make first layout visible
wrapper1.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
wrapper2.setVisibility(View.GONE);
girGridView=(GridView) findViewById(R.id.gridView1_bir);
//ListView gibi buna da adapter set ediliyor.
girGridView.setAdapter(new ImageAdapter(this));
girGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long arg3) {
Toast.makeText(getApplicationContext(), GridViewConfig.getResim_list().get(position), Toast.LENGTH_SHORT).show();
}
});
}
});
I have seven equal Buttons in LinearLayout
<?xml version="1.0" encoding="utf-8"?>

Their OnClickListener is also equal (and initializing too):
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.calendar_row, null);
}
final Button btn_mon = (Button)convertView.findViewById(R.id.btn_mon);
final Button btn_tus = (Button)convertView.findViewById(R.id.btn_tus);
final Button btn_wen = (Button)convertView.findViewById(R.id.btn_wen);
final Button btn_thu = (Button)convertView.findViewById(R.id.btn_thu);
final Button btn_fri = (Button)convertView.findViewById(R.id.btn_fri);
final Button btn_sat = (Button)convertView.findViewById(R.id.btn_sat);
final Button btn_sun = (Button)convertView.findViewById(R.id.btn_sun);
btn_mon.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_mon, weekdays.get(0).data); }});
btn_tus.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_tus, weekdays.get(1).data); }});
btn_wen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_wen, weekdays.get(2).data); }});
btn_thu.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_thu, weekdays.get(3).data); }});
btn_fri.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_fri, weekdays.get(4).data); }});
btn_sat.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_sat, weekdays.get(5).data); }});
btn_sun.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_sun, weekdays.get(6).data); }});
onCalBtnClick method:
private void onCalBtnClick(Button btn, int day){
Log.d("debug", String.valueOf(day));
btn.setTextColor(mContext.getResources().getColor(R.color.orange));
//selectedYear, month are global
Intent intent = new Intent();
intent.putExtra("year", selectedYear);
intent.putExtra("month", month);
intent.putExtra("day", day);
setResult(RESULT_OK, intent);
finish();
}
However, if I put Log.d into onCalBtnClick method (it is called from each clicklistener), only middle three buttons work. Two buttons from left side (btn_mon, btn_tus) and two buttons from right side (btn_sat, btn_sun) don't react on user click. Middle buttons work fine.
This is similar question Android LinearLayout make button doesn't work but my layout file corresponds to pattern in the answer there and buttons don't work nevertheless
UPDATE
When I removed fixed button height and width in layout file (from 50dp to wrap_content), all buttons started to work!
However, now it doesn't look as needed. There's space needed between text's on buttons.
And main question: WHY?
If you using weights in your layout, you are telling that it should be filled with some objects with some proportions. It just opposite to "wrap_content". With weights outer layout defines size of inner views, while "wrap_content" means that outer layout size is defined by inner views.
Please decide what approach is better in that case - removing weights or fixed inner views sizes.
set your Linear Layout's Width and Height to FILL_PARENT .it will work for sure.
Try to declare all your setOnClickListener for buttons outside of your adapter class and after initialization of weekdays array.
That will solve your problem.
Or try to set condition like this for all buttons :
if (btn_mon != null && position < weekdays.size()) {
btn_mon.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { onCalBtnClick(btn_mon, weekdays.get(0).data); }});
}
I'm using a listview. Before adding the main list items to the listview, i add a header with to the listview using addheaderview(v). header have two buttons.
In logcat..it gives problem at
btnhome.setOnClickListener(new View.OnClickListener() {
and it force close.
plz help me where is error in below code.
waiting for your reply
thanx in advance
enter code here
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.games_by_category);
Global globalclass=((Global)getApplicationContext());
globalclass.setpageno(0);
lstview =(ListView)findViewById(android.R.id.list);
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.header, null);
//View v = getLayoutInflater().inflate(R.layout.header, null);
v.setMinimumHeight(10);
lstview.addHeaderView(v);
btnhome=(Button)findViewById(R.id.btnHome);
btnhome.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
btnhome.setTextColor(Color.BLACK);
Global globalclass=((Global)getApplicationContext());
Intent inte=new Intent(GamesByCatActivity.this,HotGamesActivity.class);
startActivity(inte);
}
});
Just get the Buttons from the header view and set the onClickListener.
View header;
Button headerButton = header.findViewById(R.id.btn1);
headerButton.setOnClickListener(this);
listView.addHeaderView(header);
I am not able to understand your problem. What do you want to do? If you have ListView and header then you use LinearLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="#+id/_lv_babies" >
</ListView>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#color/blue_email"
>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Edit" android:textSize="15dp" android:padding="10dp"
android:layout_margin="5dp" android:textColor="#color/black"
android:id="#+id/_btn_edit"/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add" android:textSize="15dp" android:padding="10dp"
android:layout_margin="5dp" android:textColor="#color/black"
android:id="#+id/_btn_add"/>
</RelativeLayout>
</LinearLayout>
This is the example you can use like this.
For your button click....if its works then tick on right click or accept my answer.
protected void setXmlComponents(){
_btn_add =(Button)findViewById(R.id._btn_add);
_btn_edit =(Button)findViewById(R.id._btn_edit);
}
protected void setListener(){
_btn_add.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
_btn_edit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
}
I want to add text under a image button, which are also clickable, and will be redirected to the same activity as the image button. basically it's like the app list in any android phone, e.g.
If you have your ImageButton declared in XML, then just put it into a LinearLayout which also contains a TextView and set the onClickListener on the LinearLayout. The structure would be like
<LinearLayout
... > <!-- This is the LinearLayout for the xml document -->
<!-- Some other layout code here if you please -->
<LinearLayout
android:id="#+id/linLayout"
... >
<ImageButton
... />
<TextView
... />
</LinearLayout>
</LinearLayout>
And then in your java:
LinearLayout layout = (LinearLayout)findViewById(R.id.linLayout);
layout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
If you're adding each ImageButton dynamically via java code, then it will still maintain the same structure. Let me know if I need to add anything.
setAlpha and do the below
<Button
android:id="#+id/comparePack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:onClick="compareButtonClick"
android:text="#string/compare"
android:drawableTop="#drawable/compare1edit"
android:gravity="left|center_vertical" />
if you want to create this king of list use gridview
and in getview method inflate customlayout with imageview and textview
Also you can set onClickListener to TextView
<!-- Some other layout code here if you please -->
<LinearLayout
android:id="#+id/linLayout"
... >
<ImageButton android:id="#+id/btn1"
... />
<TextView android:id="#+id/tv1"
... />
</LinearLayout>
java code:
ImageButton btn1 = (ImageButton) findViewById(R.id.btn1);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myClick();
}
});
TextView tv1 = (TextView) findViewById(R.id.tv1);
tv1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myClick();
}
});
