Display ActionMode over Toolbar

Question

I am trying to use the android.view.ActionMode with the new android.support.v7.widget.Toolbar, in addition to the traditional android.app.Act

Answer 1

Since you are using the Toolbar, I also assume you are using the AppCompatActivity and have replaced the built in ActionBar with your custom Toolbar using setSupportActionBar(toolbar);

First of all ensure you are importing the correct namespace:

import androidx.appcompat.view.ActionMode;
// Or
import android.support.v7.view.ActionMode;

and NOT

import android.view.ActionMode;

then use

_actionMode = startSupportActionMode(this);

and NOT

_actionMode = startActionMode(this);

Answer 2

Try this in your theme:

<item name="windowActionModeOverlay">true</item>

Answer 3

I think the one thing people are not making clear is that the line

<item name="windowActionModeOverlay">true</item>

is placed in the Base theme i.e AppTheme and not the AppTheme.NoActionBar

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionModeOverlay">true</item>
</style>

<style name="transparent" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsTranslucent">true</item>
</style>


<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

Answer 4

This is the solution I made.

In my onCreateActionMode method of ActionMode.Callback, I add this:

StandaloneActionMode standaloneActionMode = (StandaloneActionMode) actionMode;
Field mContextView;
try {
     mContextView = StandaloneActionMode.class.getDeclaredField("mContextView");
     mContextView.setAccessible(true);
     View contextView = (View) mContextView.get(standaloneActionMode);
     MarginLayoutParams params = (MarginLayoutParams) contextView.getLayoutParams();
     params.topMargin = mToolbar.getTop();
  } catch (NoSuchFieldException e) {
            e.printStackTrace();
  } catch (IllegalAccessException e) {
            e.printStackTrace();
  } catch (IllegalArgumentException e) {
            e.printStackTrace();
  }

It works for me.

I have tried all the methods above, but it still doesn`t work. And then, I tried the below method:

    private class ActionModeCallback implements ActionMode.Callback {
    @Override
    public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
        actionMode.getMenuInflater().inflate(R.menu.note_find_action, menu);
        return true;
    }

    @Override
    public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) {
        ((AppCompatActivity) getActivity()).getSupportActionBar().hide();
        return false;
    }

    @Override
    public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
        return false;
    }

    @Override
    public void onDestroyActionMode(ActionMode actionMode) {
        ((AppCompatActivity) getActivity()).getSupportActionBar().show();
    }
}

Here, I used action mode and startSupportActionMode method of support library. At the same time I have also tried to modify the theme of given activity. Surely, it doesn`t work. So, if you really have no better choice you may try this one.

Just recently, I have found that I used the Colorful frame to enable multiple theme of my app, this will change the theme in code. When I tried to modify the style in this framework, it works.

Hope it works.

find your AndroidManifest.xml ,next add below code in your application or Activity theme

<item name="windowActionModeOverlay">true</item>

so like:

<style name="WorkTimeListTheme" parent="AppTheme.NoActionBar">
        <item name="windowActionModeOverlay">true</item>
        <item name="actionModeBackground">@color/theme_primary</item>
    </style>
