推荐答案

我发现了may错误的解决方案，我必须添加appCompatActivity的implements覆盖方法.下面是我修复它的代码.

I found the solution of may error, i have to add the implements override methods of appCompatActivity. Below is the code by which i have fix it.

package com.drawer.sample;

import android.os.Bundle;
import android.support.v7.view.ActionMode;
import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.app.AppCompatCallback;

public class MainActivity extends AppCompatActivity implements AppCompatCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar mToolbar =  (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

    }

    @Override
    public void onSupportActionModeFinished(ActionMode mode) {
        // TODO Auto-generated method stub
        super.onSupportActionModeFinished(mode);
    }

    @Override
    public void onSupportActionModeStarted(ActionMode mode) {
        // TODO Auto-generated method stub
        super.onSupportActionModeStarted(mode);
    }
}

我可以添加状态栏以及动作栏. :)

And i can add the statusbar as well actionbar. :)
