Question

我正在使用可折叠的工具栏和具有3个选项卡的Tabhost。但不幸的是，Tabhost覆盖了工具栏。我希望Tabhost位于工具栏的正下方。

MainActivity.java

package com.chandra.user.newstrailerapp.app;

import android.app.LocalActivityManager;
import android.content.Intent;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.TabHost;

public class MainActivity extends AppCompatActivity {

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

    TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
    toolbar = (Toolbar)findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    LocalActivityManager mLocalActivityManager = new LocalActivityManager(this, false);
    mLocalActivityManager.dispatchCreate(savedInstanceState);
    tabHost.setup(mLocalActivityManager);



    //RecycleVIew
    RecyclerView recyclerView=(RecyclerView)findViewById(R.id.list);
    recyclerView.setHasFixedSize(true);

    //to use RecycleView, you need a layout manager. default is LinearLayoutManager
    LinearLayoutManager linearLayoutManager=new LinearLayoutManager(this);
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    recyclerView.setLayoutManager(linearLayoutManager);
    YoutubecardAdapter adapter=new YoutubecardAdapter(MainActivity.this);
    recyclerView.setAdapter(adapter);

}
}

activity_main.xml中
