具有溢出菜单的自定义操作栏布局

Question

I use the actionbarsherklock library with custom action bar look like this:

My custom implement:

  ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

    // Do any other config to the action bar
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().setDisplayShowHomeEnabled(false);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // set custom view
    View actionBarView = getLayoutInflater().inflate(
            R.layout.action_bar_default, null);

    View btnMenuLeft= actionBarView.findViewById(R.id.btnMenuLeft);
    btnMenuLeft.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            toggle();
        }
    });

    View btnMenuShare= actionBarView.findViewById(R.id.btnMenuShare);
    ActionBar.LayoutParams params = new ActionBar.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    actionBar.setCustomView(actionBarView, params);

    // Hide the home icon
    actionBar.setIcon(android.R.color.transparent);
    actionBar.setLogo(android.R.color.transparent);

And here is the custom layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/nav_bar_bg"
android:gravity="center"
android:orientation="horizontal" >

<!-- menu button -->
    <ImageButton
        android:id="@+id/btnMenuLeft"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/list_btn"
        android:clickable="false"
        android:duplicateParentState="true"
        android:focusable="false" />

    <!-- logo -->
    <ImageView       
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:src="@drawable/app_logo" />

    <!-- share button -->
    <ImageButton
         android:id="@+id/btnMenuShare"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/action_btn"
        android:clickable="false"
        android:duplicateParentState="true"
        android:focusable="false" />

The problem is that I want add an over flow menu to share button like this one:

Please tell me how can I do that with the custom action bar layout.

Answer 1

Seem there is no right way to solve this problem, so I tried a hack by using popup windows with list adapter to fake action bar overflow menu.
It look like this example: http://rajeshandroiddeveloper.blogspot.com/2013/07/android-popupwindow-example-in-listview.html

Just override this two methods to call overflow menu in your activity which one is extending ActionBarActivity :

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.your_menu, 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();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
