我有一个链接不同 xml 布局的按钮栏，但是当我尝试单击不同的按钮时，我只能到达一个而不返回到其他的。抱歉，提前麻烦了，还是有点新手。这是我在这里的第一篇文章，但经常引用这个网站。提前致谢。

更新。XML 看起来不错，谢谢。我仍然遇到以前遇到的同样问题。我为每个布局添加了活动，但我仍然遇到同样的问题，即不打算循环浏览布局。每个 java 文件看起来都和这个一样。

MainActivity.java（使用新的 .class Intent 更新）

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

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

    Button btn1 =(Button)findViewById(R.id.btn1);
    Button btn2 =(Button)findViewById(R.id.btn2);
    Button btn3 =(Button)findViewById(R.id.btn3);
    Button btn4 =(Button)findViewById(R.id.btn4);

    btn1.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent();
            myIntent = new Intent(getApplicationContext(), MainActivity.class);
            myIntent.setAction(Intent.ACTION_VIEW);
              myIntent.setData(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
            setContentView(R.layout.activity_main);
            return;
        }
    });

    btn2.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent();
            myIntent = new Intent(getApplicationContext(), MainAgil.class);
            myIntent.setAction(Intent.ACTION_VIEW);
            myIntent.setData(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
            setContentView(R.layout.agil_main);
            return;
        }
    });


    btn3.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent();
            myIntent = new Intent(getApplicationContext(), MainInt.class);
            myIntent.setAction(Intent.ACTION_VIEW);
            myIntent.setData(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
            setContentView(R.layout.int_main);
            return;
        }
    });


    btn4.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent();
            myIntent = new Intent(getApplicationContext(), MainMisc.class);
            myIntent.setAction(Intent.ACTION_VIEW);
            myIntent.setData(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
            setContentView(R.layout.misc_main);
            return;
        }
    });

}}

Define your button bar in a separate XML layout. In every XML you need that bar include that button bar using <include/> tag. And in every activity in which XML you have included the button bar handle the onclick of the buttons separately.
