Android can not remove button

I am trying to remove a button when the button itself is tapped, I am trying the following:
View.OnClickListener getOnClickDoSomething(final Button button) {
return new View.OnClickListener() {
public void onClick(View v) {
tagsView.removeView(button);
}
};
}
This code is working, but when I add the following line of code:
editText.setText(button.getText());
The code stops working and the button does not get removed. I add it like so:
View.OnClickListener getOnClickDoSomething(final Button button) {
return new View.OnClickListener() {
public void onClick(View v) {
editText.setText(button.getText());
tagsView.removeView(button);
}
};
}
What is the problem here?

use this in your OnClick method
button.setVisibility(view.GONE);
Your code will look like this
View.OnClickListener getOnClickDoSomething(final Button button) {
return new View.OnClickListener() {
public void onClick(View v) {
editText.setText(button.getText());
button.setVisibility(view.GONE);
}
};
}
Or Try this
Button mybtn = (Button)findViewById(R.id.mybtn_id);
mybtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mybtn.setVisibility(view.GONE); // or (view.INVISIBLE)
}
});

Depending on what you're trying to achieve, something like deejay proposed would work just fine. If want the button to hide, call button.setVisibility(View.INVISIBLE). However, if you are trying to dismiss it completely from the view hierarchy, call button.setVisibility(View.GONE).

just set button visibility to false

Obviously button.setVisibility(View.GONE) comes to mind but if it doesn't work you should look one level above for the source of the bug. Maybe you don't set OnClickListener you created to the button and hence nothing happens?

Launch new contentView onClick (to obtain new window from another XML layout)

I'm trying to execute a new contentView this way. What am I missing? I get a force close onClick.
final Button btnStatus = (Button) findViewById(R.id.Status);
btnStatus.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent = getIntent();
startActivity(intent);
setContentView(R.layout.newlayout);
}
});

This is just wrong. You can do one of two things here.
Not recommended but could work for what you are doing
Simply using setContentView(R.layout.newlayout) will set the new layout assuming newlayout.xml is a layout in your layout folder
public void onClick(View v)
{
setContentView(R.layout.newlayout);
}
Recommended
Create a new Activity and set the content in it to this new layout and call that Activity in your onClick()
public void onClick(View v)
{
Intent intent = new Intent(CurrentActivityName.this, NextActivityName.class);
startActivity(intent);
}
});

if you want to change layout then try to,
{setContentView(R.layout.newlayout);}
if you want to change activity, then try to intent to forward another activity, and check also to entry of this activity in manifest file in android.

Displaying ImageButtons in an Activity

I want to display ImageButtons like in an activity in my android application.
Now when i click on any one of the ImageButton, it should start a new Activity.
I don't know whether this type of view is possible or not. ?

This will help you,

Also this one

You should check the Gallery widget.

yah that's possible.like an button clck listener there is also a listener for the image button .by that calling the another activity a

You can try the below code:-
ImageButton imageButton = new ImageButton(getApplicationContext());
imageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent("<activity_class_name or intent action");
context.startActivity(intent);
}
});

Changing Activity on a clickable layout

I have this clickable LinearLayout view, im trying to have it change Activity when clicked by every time i click the object i get a error.
final LinearLayout lindet = (LinearLayout) findViewById(R.id.detials);
lindet.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(SellingActivity.this, DetailsActivity.class);
startActivity(i);
finish();
}
});

Did you remember to add the DetailsActivity to the AndroidManifest?

Supporting Macarse I would add that use SellingActivity.this.finish() instead of finish()
I believe this will prove to be your problem solver.

Button in slidingdrawer!

I'm having a button in a sliding drawer in a Android Application. The problem is it does not seem to react to any clicks as normal buttons do.
I'm guessing the problem is that it's a different view than buttons on the normal view.
If I implement a button the normal way like this
myAgenda = (Button)findViewById(R.id.BtnMyAgenda);
myAgenda.setOnClickListener(this);
public void onClick(View v) {
switch(v.getId()){
case R.id.BtnMyAgenda:
test.setAnimation(leftLeft);
test.startAnimation(leftLeft);
break;
}
I'm guessing there is something wrong with the above code since the button is in a SlidingDrawer and not in the "normal" view.
Any ideas how to fix the problem?

Here is the code
Register with event listner like below code
button.setOnClickListener(clickButtonListener);
and create this listner for button
private OnClickListener clickButtonListener= new OnClickListener()
{
#Override
public void onClick(View v)
{
if(v == button)
{
}
}
}

I actually found the solution to the problem, I simply created a new view.onclicklistener specific to that button.
final Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
