我是 android 开发的新手（我是 ac#asp.net 家伙）正在尝试编写一个与 api10 及更高版本兼容的应用程序，并且我在 if then else 语句中使用不同的 xml 处理屏幕方向。我在每个 xml 中有 6 个 imageView 控件（名为 imageView1 - imageView6），它们是 onClick 事件（我不喜欢 imagebutton 在图像上放置填充的方式）。这样做的原因是我必须根据方向更改图像大小，因此总共有 12 张图像（如果包括高亮图像，则为 24 张）。

如果我将两个 xmls imageViews 作为 imageView1 留给 imageView6，应用程序不会崩溃，但是，我无法独立处理 12 个图像中的每一个。我只和他们中的 6 个一起工作。当我将 xml 的 imageView 更改为 imageView7 到 imageView12 时，应用程序完全崩溃，我不知道为什么？这似乎是我忽略了一些非常简单的东西，但我不知道它是什么。这是我的代码：

package com.firstmelissa.FirstBaptistMelissa;

import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.Display;
import android.view.Menu;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity implements View.OnClickListener {

ImageView display1
ImageView display2;
ImageView display3;
ImageView display4;
ImageView display5;
ImageView display6;
ImageView display7;
ImageView display8;
ImageView display9;
ImageView display10;
ImageView display11;
ImageView display12;

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main_layout, menu);
        return true;
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Display getOrient = getWindowManager().getDefaultDisplay();
        if (getOrient != null)
        {
            int orientation = getResources().getConfiguration().orientation;   
            if (orientation == 1) {
                // Portrait
                setContentView(R.layout.main_layout);

            display1 = (ImageView) findViewById(R.id.imageView1);

            ImageView image2 = (ImageView) findViewById(R.id.imageView2);
            display3 = (ImageView) findViewById(R.id.imageView3);

            ImageView image5 = (ImageView) findViewById(R.id.imageView5);
            display6 = (ImageView) findViewById(R.id.imageView6);
            ImageView image6 = (ImageView) findViewById(R.id.imageView6);

        }
        else if (orientation == 2) {
            // Landscape
            setContentView(R.layout.main_landscape);
            //Intent intent = new Intent(this, MainActivityland.class);

            display11 = (ImageView) findViewById(R.id.imageView11);
            ImageView image11 = (ImageView) findViewById(R.id.imageView11);
            display12 = (ImageView) findViewById(R.id.imageView12);
            ImageView image12 = (ImageView) findViewById(R.id.imageView12);

我知道这很简单！case R.id.imageView6:这是and之间缺少的 break 语句case R.id.imageView7:！这完全解决了我的问题，感谢您帮助定位它！
