I have created custom Preference dialog from answer of this link.
Now I want click event on that button in my ActivityPreferenceScreen activity class.
How can i achieve this ?
Add the following attribute in your Activity:
OnClickListener prefButtonListener = new OnClickListener() {
public void onClick(View view)
{
Log.v("Btn", "Clicked");
}
};
In the place you instanciate the EditTextPreferenceWithButton class, add this code:
editTextPreferenceWithButton.attachButtonListener(prefButtonListener);
And then, add following in your EditTextPreferenceWithButton class :
public void attachButtonListener(OnClickListener listener) {
this.button.setOnClickListener(listener);
}
}

I have two java class and two layout for both the class.
Each layout is having one button in it.
Both classes are extending Activity.
Now in first layout I used include tag like this
<include
android:id="#+id/clicked"
layout="#layout/activity_main" />
I can now see two buttons but the second button is not working.
First You have to declare and initialise the include view and then decalre and initialise both buttons using view.findViewById() method as follows:
View includeView = (View)findViewById(R.id.clicked);
Button button1 = (Button)includeView.findViewById(R.id.button1ID); //decalre button like this
Button button2 = (Button)includeView.findViewById(R.id.button2ID);
And then set their onClickListeners
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//code whatever you want to do here
}
});
button2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//code whatever you want to do here
}
});
** EDIT **
Fixed the typo. Should be includeView on the findViewById.
Good explanation though!
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?
I am using Gabrielemariotti's Cardslib library to implement card layout in my android application. I am using a custom layout for my cards. Below is the code for creating custom cards:
Card card = new Card(getActivity().getApplicationContext(), R.layout.status_card);
card.setTitle("sample title");
I have three buttons at the bottom of my card (like buttons in Facebook android app). I want to set onClickListener for these buttons. But I am not sure how to do that.
Please help me here.
Thanks,
You have to define your layout.
Then create a Card with this layout, and override the setupInnerViewElements method.
Inside this method you can define your OnClickListener on your buttons, and you can access to all card's values.
public class CustomCard extends Card {
/**
* Constructor with a custom inner layout
*
* #param context
*/
public CustomCard(Context context) {
super(context, R.layout.carddemo_mycard_inner_content);
}
#Override
public void setupInnerViewElements(ViewGroup parent, View view) {
//Retrieve button
Button myButton = (Button) view.findViewById(R.id.myButton);
if (myButton != null) {
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "Click Listener card=" + getId(),
Toast.LENGTH_LONG).show();
}
});
}
}
}
I have an easy solution for this.
So another way to add onClick listeners, which is a bit easier, is through the XML.
In the xml for the button, you add this line:
android:onClick="methodName"
Where 'methodName' is obviously the name of a method. This will call the method whenever the button is clicked. The next step is obvious - just go into your java activity and create the method that you want called, making sure to take the View as a parameter. So you'd have something like this in your activity class:
public void methodName(View view) {
Log.v("appTag","BUTTON WAS PRESSED");
//whatever you want to do here
}
This is a shortcut to creating a whole onClickListener.
Hope that helps. Good luck :)
EDIT:
Remember, you're passing in a view here, so you can get whatever you want off of that view. Since you commented that you need to get the text off of your card, I'll show you how to do that.
Here is your method for this case:
public void methodName(View view) {
Log.v("appTag","BUTTON WAS PRESSED");
TextView textFromCard = view.findViewById(R.id.THE_ID_YOU_GAVE_YOUR_TEXTVIEW_IN_THE_XML);
String textFromTextView = textFromCard.getText().toString();
//do whatever you want with the string here
}
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
}
I am new to android. I want to set OnclickListner for different buttons which are located in different xml layouts.
You can also use a definition like that directly in the XML-file:
<Button android:onClick="myClickHandler" />
After that you can create the method "myClickHandler" in your Code like that:
class MyActivity extends Activity {
public void myClickHandler(View target) {
// Do stuff
}
}
Something like this:
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
}
});
Then all you need to do is reference the different buttons by their different ids set in the XML
