I want to show Toast on actionItem() function inside. But it doesn't now showing Toast.
If I call
Context context = getApplicationContext();
Before actionItem() then the app crashes.
import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
public class ShowWebViewActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.show_web_view);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_show_web_view, menu);
return true;
}
@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();
//noinspection SimplifiableIfStatement
// if (id == R.id.action_settings) {
// return true;
// }
switch (item.getItemId()) {
case R.id.action_settings:
actionItem();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
// Context context = getApplicationContext() makes app to crash why??
public void actionItem(){
// Toast function should call here. But not working
Context context = getApplicationContext();
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG);
}
}

You missed the show()
function.
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG).show();

show()
is missing use the following code
public void actionItem(){
// Toast function should call here. But not working
Context context = getApplicationContext();
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG).show();
}

Show()
is missing from your code. Kindly refer to my code:
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG).show();

You missed show()
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG);
it should be:
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG).show();

Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG);
should be:
Toast.makeText(context, "Action Setting Selected", Toast.LENGTH_LONG).show();
You would have got an IDE warning also for this
