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?

Say I have defined an onClickListener for a TextView and I want to trigger it once without having to click on it - Is this possible?
you just have to call performClick() on it
textView.performClick()
textView= (TextView) findViewById(R.id.button);
textView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Add your code here
}
});
to perform automatic click use below
textView.performClick();
What is the logic of adding text to an edittext when button is pressed. Like in simple calculator, when u press a button the numbers will be shown to the edittext. What do you call that logic? I need a developers explanation.
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
edittext.setText("text");
}
});
The logic is get the text from button and set it to the edittext,in aappending mode
Just use append() of the EditText. The Argument will be appended at the end of the Editable.
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
editText1.append("your string to add at the end.");
}
});
I want to implement a click listener for a button on my main view. My code is something like below
protected void onCreate(Bundle savedValues) {
...
// Capture our button from layout
Button button = (Button)findViewById(R.id.btnFinish);
// Register the onClick listener with the implementation above
button.setOnClickListener(mFinishListener);
...
}
private OnClickListener mFinishListener = new OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
}
};
But shows me error as follows
The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (DialogInterface.OnClickListener) MobileTrackerActivity.java /MobileTracker/src/com/example/mobiletracker line 37 Java Problem
I have no idea what to do. Please help.
You are not using the correct interface to instantiate the mFinishLinstener variable...
It is possible you have an import specifying DialogInterface and that is confusing the view.
Try specifying View.OnClickListener explicitly.
private View.OnClickListener mFinishListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
}
};
As per my opinion Best way to implement On click event for the Button.
Instead of applying an OnClickListener to the button in your activity, you can assign a method to your button in the XML layout, using the android:onClick attribute. For example:
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/self_destruct"
android:onClick="selfDestruct" />
Now, when a user clicks the button, the Android system calls the activity's selfDestruct(View) method. In order for this to work, the method must be public and accept a View as its only parameter. For example:
public void selfDestruct(View view) {
// Kabloey
}
Note: The above code is given in Android SDK - Button.
try this code :::
final Button button = (Button) findViewById(R.id.btnFinish);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
}
});
Simply try this one as:
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// do something when the button is clicked
}
};
you can also use like below code..
Button button = (Button)findViewById(R.id.btnFinish);
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v)
{
//Write Your code here
}
});
You can also declare the onclick in the xml.
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:onclick="buttonClick" />
And in your code you would define the function as:
public void buttonClick(View view)
{
// handle click
}
in my app i have three buttons namely A,B and C. I want the buttons B and C to be disabled until button A is clicked. they should be ready to perform this function until button A is clicked how to do this.....
protected void onCreate(Bundle savedInstanceState)
{
buttonB.setEnabled(false);
buttonC.setEnabled(false);
}
public void onClick(View v)
{
if (v == buttonA)
{
buttonB.setEnabled(true);
buttonC.setEnabled(true);
}
}
you should write this will creating your app
myButton.setEnabled(false);
and in the button click function you should enable it by doing this.
myButton.setEnabled(true);
// assuming valid references to buttons
buttonB.setEnabled(false);
buttonC.setEnabled(false);
buttonA.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
buttonB.setEnabled(true);
buttonC.setEnabled(true);
}
});
Disable the button
myButton.setEnabled(false);
Enable the button
myButton.setEnabled(true);
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) {
}
});
