Question

在一个大项目中，我有以下代码，运行步骤是
首先运行GalleryMeno，然后运行GalleryActivityMain

GalleryMeno.java

public class GalleryMeno  extends Activity{

private Integer[] mThumbIds = {
        R.drawable.gallary_farhad1 ,
        R.drawable.gallary_farhad2,
        R.drawable.gallary_naser ,
        R.drawable.gallary_mehdi ,
        R.drawable.gallary_other ,
        R.drawable.gallary_old ,
        R.drawable.gallary_amir ,
        R.drawable.gallary_bazikonan
};

private String[] name = {
        "gallary_farhad1",
        "gallary_farhad2",
        "gallary_naser",
        "gallary_mehdi",
        "gallary_other",
        "gallary_old",
        "gallary_amir",
        "gallary_bazikonan"
};

@Override
protected void onCreate(Bundle savedInstanceState) {

    setContentView(R.layout.gallery_meno_activity);

    TextView titleName = (TextView) findViewById(R.id.title_name);
    titleName.setText("گالری تصاویر");


    //found width of Screen for Gridview
    WindowManager windowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    int densityX = display.getWidth();  

    Button btnUpdate = (Button) findViewById(R.id.update);
    btnUpdate.setVisibility(View.INVISIBLE);

    Button backButton = (Button) findViewById(R.id.backward);
    backButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-g

            finish();
        }
    });

    GridView grid = (GridView) findViewById(R.id.gridViewSms);
    grid.setAdapter(new ImageAdapter(getApplicationContext(), densityX, mThumbIds));

    grid.setOnItemClickListener(new OnItemClickListener() {

案例1：当我在Android 2.2中运行上面的代码时，我看到了一个由gridview制作的图像菜单当我点击每个项目时显示有关此项目的所有图像。（在这种情况下，所有结果都可以）

案例2：但是当我在android 4.2中运行相同的代码时通过点击项目（查看关于它的所有图像）我的程序变为退出而没有任何forceClose

例如：当我点击图片gallary_amir时，我希望来自ImageGroup7的图片的网格视图为什么？我如何修复Case2？

Answer 1

你说你没有收到任何力量，因此没有LogCat。我要说的是，因为您正在查看Android 4.2 API level 17 android:targetSdkVersion=""，请尝试将17设为16而不是LogCat，看看您是否接收If the API level of the platform is higher than the version declared by your app's targetSdkVersion, the system may enable compatibility behaviors to ensure that your app continues to work the way you expect.中的任何错误。如果您阅读android:targetSdkVersion，请说：

当您在目标较高版本上进行测试时，Android会尝试启用这些兼容性行为。可能有一些函数调用或其他一些在API版本17中发生了变化并且行为正常的东西。另一点是，尝试在您的代码中看到哪些东西已经为API 17折旧并且已经在您的代码中使用过了。始终建议使用最新的东西。

希望这在某种程度上有所帮助。
