So, my problem is that OnClickListener
doesn't work when I set android:clickable="true"
into my class.
This is MyClass
xml code:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:clickable="true">
...
...
</RelativeLayout>
MyClass.java:
public class MyClass extends RelativeLayout implements OnClickListener {
public MyClass(Context context) {
super(context);
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.book_item, this);
setOnClickListener(this);
}
public void onClick(View v) {
Log.v("TAG", "Hello");
}
...
...
}
It works fine when I set android:clickable
to false. What do I wrong?
Setting an OnClickListener
will automatically set the clickable property to true. The code you are showing is confusing though. My understanding is that your MyClass
view is the parent of the RelativeLayout
shown in the XML file.
If so, the child RelativeLayout
will get the touch events first (since it's clickable) but won't do anything with them since it doesn't have a click listener.
Just remove clickable=true
from your XML.
when you do this: android:clickable="true"
you disable the onClickListener
(its not logical but its like that..).
So set it to "false"
or just remove this line from your XML file ;)
Add id to your layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/yourId"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:clickable="true">
</RelativeLayout>
Then in java code:
public class MyClass extends RelativeLayout implements OnClickListener {
public MyClass(Context context) {
super(context);
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.book_item, this);
findViewById(R.id.yourId).setOnClickListener(this);
}
public void onClick(View v) {
Log.v("TAG", "Hello");
}
...
...
}
((RelativeLayout)findViewById(R.id.yourId)).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
//code area ...
Log.v("TAG", "Hello");
return true;
} else{
return false;
}
}
});
You can use this way too.
Instead of implementing OnClickListener to the whole class, you can set OnClickListener to each of the elements after filtering them if there are only few elements to do actions.
TextView textLogin = findViewById(R.id.textLogin);
textLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.i("click", "textLoginClicked.");
}
});
Else you should state that the elements you are going to set OnClickListener like,
textLogin.setOnClickListener(this);
Then you can use,
@Override
public void onClick(View view) {
if (view.getId() == R.id.textLogin) {
Log.i("Click", "Login clicked.");
}
}
