Adding a toolbar to PreferenceActivity through AppCompatPreferenceActivity causes overlap

Question

I went through How to add toolbars in AppCompatPreferenceActivity?

I use appcompat-v7:23.0.1andsupport-v4:23.0.1

Before using AppCompayPreferenceActivitymine, PreferenceActivityit looks without a toolbar.

Without toolbar

public class JStockPreferenceActivity extends PreferenceActivity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (savedInstanceState == null) {
            // Display the fragment as the main content.
            JStockPreferenceFragment jStockPreferenceFragment = JStockPreferenceFragment.newInstance();
            jStockPreferenceFragment.setArguments(this.getIntent().getExtras());
            this.getFragmentManager().beginTransaction().replace(android.R.id.content, jStockPreferenceFragment).commit();
    }
}

After use AppCompayPreferenceActivity, with some initialization code Toolbar, the result is as follows

The result is not as expected: -

• Toolbar overlaps with PreferenceFragment
• When touched, the Toolbarevent will be consumed PreferenceFragment. This means that when you touch the toolbar, the "Table Header" preference will be affected instead.

With toolbar

public class JStockPreferenceActivity extends AppCompatPreferenceActivity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (savedInstanceState == null) {
            // Display the fragment as the main content.
            JStockPreferenceFragment jStockPreferenceFragment = JStockPreferenceFragment.newInstance();
            jStockPreferenceFragment.setArguments(this.getIntent().getExtras());
            this.getFragmentManager().beginTransaction().replace(android.R.id.content, jStockPreferenceFragment).commit();
        }
        initToolbar();
    }

    private void initToolbar() {
        Toolbar toolbar;

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            ViewGroup root = (ViewGroup) findViewById(android.R.id.list).getParent().getParent().getParent();
            toolbar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.toolbar, root, false);
            root.addView(toolbar, 0);
        } else {
            toolbar = null;
        }

        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
}

My toolbar
