Android 全屏图像库

对不起我的英语。有一个迷你图库，当您单击图库中的图像时，它应该（图片）全屏打开。应用程序只需按下图像即可抛出。我做错了什么？ 主要活动

public class MainAcTwo extends Activity {

@SuppressWarnings("deprecation")
Gallery gallery;
ImageView bigimage;

@SuppressWarnings("deprecation")
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.two);
    gallery=(Gallery) findViewById(R.id.gallery);
    gallery.setAdapter(new ImageAdapter(this));

    gallery.setOnItemClickListener(new OnItemClickListener() {
        @TargetApi(Build.VERSION_CODES.HONEYCOMB) @SuppressLint("NewApi") public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {

            long imageId = ImageAdapter.ThumbsIds[position];

           Intent fullScreenIntent = new Intent(v.getContext(), FullScreenImage.class);
           fullScreenIntent.putExtra(MainAcTwo.class.getName(), imageId);

          MainAcTwo.this.startActivity(fullScreenIntent); 

        }
    });
}

}

}如果项目不起作用，请清理项目

 imageView.setLayoutParams( new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));


change it to

 imageView.setLayoutParams( new LinearLayout.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));

它抛出的错误是什么？在哪一行？当我单击图像时，在logCat中写入“不幸的是，MyProject已停止”：致命异常：main java.lang.ClassCastException:android.view.ViewGroup$LayoutParams不能强制转换为android.widget.LinearLayout$LayoutParams或android.widget.LinearLayout.measureVerticalandroid.widget.LinearLayout.onMeasure（LinearLayout.java:574）android.view.view.measure（LinearLayout.java:655）android.view.ViewGroup.measureChildWithMargins（ViewGroup.java:4814）android.widget.FrameLayout.onMeasure（FrameLayout.java:310）android.view.view.view.measure（view.java:15172）_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu！

       ImageView imageView = (ImageView) findViewById(R.id.fullImage);
