AppCompatActivity: detect touches on title?-CodePudding

In case of an AppCompatActivity with title (set by setTitle call), (how) can I detect touches on this title section:

In case this is not (easily) possible, I'm populating this activity with setContentView.

Here is my simplified layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:id="@ id/fl"/>

</LinearLayout>

fl will be replaced by getSupportFragmentManager().beginTransaction().replace with a PreferenceFragmentCompat.

I wish to detect touches either on the titlebar, or underneath the preference items.

However I tried to call setOnTouchListener on fl (FrameLayout fl = findViewById(R.id.fl)), and it's never called.

CodePudding user response：

set the clicklistener on toolbar since you are using the setTitle for setting the title.

Toolbar toolbar = findViewById(R.id.action_bar);


if(toolbar != null) {
    for (int i = 0; i < toolbar.getChildCount(); i  ){

        View child = toolbar.getChildAt(i);

        if(child instanceof TextView || child instanceof ImageView) {
            child.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //Show some toast or log message
                }
            });
        }
    }
}

Let me know if this works
