我正在制作一个游戏，我正在制作一个具有 3 个不同视图（监狱、院子和沙子）的 LevelSelect 类，我曾经有多个意图，但如果我这样做，就没有好的方法来关闭我的应用程序，并且它不会很好地返回。

我也尝试使用该setContentView()方法，但事实证明它无法加载与视图相关的类，然后我尝试组合该类，但该类无法初始化当前视图之外的对象。所以我的问题是：如何在不启动新活动的情况下使用多个视图？

package com.muttgames.shadowpuzzle;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;

public class LevelSelect extends Activity implements OnClickListener{




protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.jail_level_view);

    //Defining Inflater
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    //Defining sandView layout
    RelativeLayout jailView =  (RelativeLayout) findViewById(R.id.jail_level);
    View innerViewsJailView = inflater.inflate(R.id.yard_level, jailView, true);

    View jailMenu = innerViewsJailView.findViewById(R.id.jail2menu);
    jailMenu.setOnClickListener(this);

    //Defining sandView layout
    RelativeLayout yardView =  (RelativeLayout) findViewById(R.id.yard_level);
    View innerViewsYardView = inflater.inflate(R.id.yard_level, yardView, true);

    View yardMenu = innerViewsYardView.findViewById(R.id.yard2menu);
    yardMenu.setOnClickListener(this);

    //Defining sandView layout
    RelativeLayout sandView =  (RelativeLayout) findViewById(R.id.sand_level);
    View innerViewsSandView = inflater.inflate(R.id.sand_level, sandView, true);

    View sandMenu = innerViewsSandView.findViewById(R.id.sand2menu);
    sandMenu.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    switch(v.getId()){
    case R.id.jail2menu:
        finish();
        break;
    case R.id.yard2menu:
        finish();
        break;
    case R.id.sand2menu:
        finish();
        break;
    }
}
}

我确实意识到这是一个非常小的课程，但我会做一些小试，以防止自己不得不一次又一次地编写大量代码。

这部分的错误是我初始化了 yardMenu 和 sandMenu 按钮，而它们不在R.layout.jail_level_viewxml 文件中。

这段代码是为了在有人想要返回时停止 levelselect 活动main_activity。

我怎么能改变它，而不是关闭活动，我可以将它更改为activity_mainxml 文件。

xml 文件（它们看起来几乎都一​​样，颜色等方面的细微调整......：

你需要一个布局充气器和一个容器。制作例如“sandMenu”一个LinearLayout，然后在代码中：

sandMenu.removeAllViews();
LayoutInflater inflater = (LayoutInflater) .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View innerViewsSandMenu = inflater.inflate(R.layout.yourLAYOUT, sandMenu, true);

稍后您可以通过这种方式访问​​ sandMenu 的内部视图：

innerViewsSandMenu.findViewById(R.id.....
