在线性布局内以编程方式崩溃添加多个linearlayout

Question

我想添加一个线性布局，该布局在用户从本地选择照片然后在（父）linearlayout中显示后立即具有图像和textview。 添加第一个linearlayout没问题，但是一旦我想输入第二个linearlayout，应用程序就会崩溃。

JAVA文件

public class newExpense extends Fragment {

ImageView addImage;
LinearLayout imageList;
final int RQS_LOADIMAGE = 0;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.new_expense_copy, container, false);  

    addImage = (ImageView) rootView.findViewById(R.id.addImage);
    addImage.setOnClickListener(buttonSaveOnClickListener);

    imageList = (LinearLayout) rootView.findViewById(R.id.imageList);

    return rootView;
}

ImageView.OnClickListener buttonSaveOnClickListener
= new ImageView.OnClickListener(){

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("Select an option")
               .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       // User cancelled the dialog
                   }
               })
               .setItems(R.array.addImage, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int which) {

                       if (which == 0) {
                           Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                           startActivityForResult(takePicture, RQS_LOADIMAGE);

                       } else {
                           Intent pickPhoto = new Intent(Intent.ACTION_PICK,
                               android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                           startActivityForResult(pickPhoto , RQS_LOADIMAGE);
                       }
                   } 
               });
            builder.show();
    }
};

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == getActivity().RESULT_OK){
        switch(requestCode){
        case RQS_LOADIMAGE:
            Uri imageUri = data.getData();

            LinearLayout injecterLayout = (LinearLayout) getActivity().getLayoutInflater().inflate(R.layout.image_list, imageList, false);

            ImageView img = (ImageView) injecterLayout.findViewById(R.id.imageView);
            TextView txt = (TextView) injecterLayout.findViewById(R.id.textView1);
            img.setImageURI(imageUri);
            txt.setText(imageUri.getLastPathSegment().toString());
            imageList.addView(injecterLayout);

            break;  
        }
    }
}

}

有人可以帮忙修改一些代码吗？ 感谢帮助。

Answer 1

您的内存不足，更确切地说是堆空间不足。 您的应用程序只能使用多少堆空间-在旧的Android设备上只有16MB的空间，在高分辨率的新设备上可能只有64MB的空间。 无论是什么，您都可能在位图上使用了所有内容。

您可以使用MAT找出正在使用堆空间的位置 。
