I have these menu items in my menu_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<item android:id="@+id/action_restart" android:title="Restart"
android:orderInCategory="1" />
<item android:id="@+id/action_clear" android:title="Clear"
android:orderInCategory="2" />
<item android:id="@+id/action_update" android:title="Update"
android:orderInCategory="3" />
<item android:id="@+id/action_about" android:title="About"
android:orderInCategory="4" />
<item android:id="@+id/action_try_restart" android:title="Try Restart"
android:orderInCategory="5" />
</menu>
And I have this in my onOptionsItemSelected
method:
@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 == R.id.action_restart) {
Toast.makeText(MainActivity.this, "Restart...", Toast.LENGTH_LONG).show();
}
if (id == R.id.action_clear) {
Toast.makeText(MainActivity.this, "Clear...", Toast.LENGTH_LONG).show();
}
if (id == R.id.action_update) {
Toast.makeText(MainActivity.this, "Update...", Toast.LENGTH_LONG).show();
}
if (id == R.id.action_about) {
Toast.makeText(MainActivity.this, "About...", Toast.LENGTH_LONG).show();
}
if(id == R.id.action_try_restart) {
// how to click / trigger the "action_restart" from here?
}
return super.onOptionsItemSelected(item);
}
I have tried with:
MenuItem actionRestart = (MenuItem) findViewById(R.id.action_restart);
actionRestart; //
But actionRestart
reference doesn't offer anything like click
, trigger
, etc.
I'd also like to note that I'm new to Android development and I come from PHP/JavaScript background, so this level of Java OOP is all new to me.
Use the method performIdentifierAction
, like this:
menu.performIdentifierAction(R.id.action_restart, 0);
