I want to create an event on toolbar's back arrow dynamically. How can I set back arrow in the Android toolbar and also apply click listener?
by adding
android:parentActivityName="com.stayapt.Home_Activity"
in manifest file and its working fine. But it will take me always on Home_Activity I want to set it Dynamically.

try this :
android.R.id.home it will handle your toolbar's back event.
@Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // todo: goto back activity from here return true; } return true; }

You need to only add : (For adding back arrow at Toolbar)
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
In your OnCreate function and Your activity should Extend AppCompatActivity
For Handle its Dynamic Click event :
Just add this to your Menu Function
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == android.R.id.home) {
onBackPressed(); //do here something what you want on clicks on the Home/Up button
}
return super.onOptionsItemSelected(item);
}
