How to programmatically trigger/click on a MenuItem in Android?

Solution 1

Use the method performIdentifierAction, like this:

menu.performIdentifierAction(R.id.action_restart, 0);

Solution 2

You should manually call your listener, with required item as parameter.

MenuItem actionRestart = (MenuItem) findViewById(R.id.action_restart);
onOptionsItemSelected(actionRestart);

Solution 3

As far as I know, there is no mechanism in the SDK that lets you do this. It's certainly not standard practice to do this sort of thing.

I recommend decoupling your logic from the actual UI as much as possible, so you end up not needing to simulate a click to trigger the action. Since you're a Web developer, this should come fairly easily to you.

In this case, you'd want to refactor the toasts into a separate method (or multiple methods), and then call that both when the menu item is clicked and when you want to trigger it manually.

Alternatively, you could try taking the MenuItem returned by findViewById() and passing it to your handler there. But I have no idea if that'll work.

Solution 4

I would like to share my solution as well here. Instead of trying to click programmatically a menu item, I created a separate method for menu item click, and call it anywhere where I need to click menu item. OnOptionsItemSelected method looks as follows. As you can see I moved click logic to a separate method.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == android.R.id.home) {
        homeClicked();
    }
    return super.onOptionsItemSelected(item);
}
private void homeClicked(){
    ...
}

Now you can call homeClicked anytime you need to click menu item programmatically.

Solution 5

Even though it's not the best way to do,

MenuItem item_your_choice;

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.your_menu, menu);
    item_your_choice = menu.findItem(R.id.item_your_choice);
    return super.onCreateOptionsMenu(menu);
}

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case item_your_choice:
           //do whatever you want
            break;
        }
   return super.onOptionsItemSelected(item);
}

just Call from any method

onOptionsItemSelected(item_you_choice);

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.

I will try this too! I've made a separate method, as I have described in Veselin Romic's answer up above. Thank you too.

This will override all of the MenuItem's interface method, which makes your code messy
