我有一个TabHost和4个不同的活动。在第一个标签中，我可以选择从图库中选择图像或从相机拍摄照片。现在，我使用public void onActivityResult（int requestCode，int resultcode，Intent intent）方法..但是，它没有在TabHost中调用..没有tabHost它工作正常...如何解决这个问题。这是我的代码..请检查我的整个代码。谢谢你提前..
tblTreePhoto.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(getParent());
alertDialog.setTitle("Select Photo");
alertDialog.setPositiveButton("Take Photo", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface arg0, int arg1)
{
if(Tree_Image.count<3)
{
Intent i1 = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File out = Environment.getExternalStorageDirectory();
out = new File(out, "newImage.jpg");
i1.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));
getParent().startActivityForResult(i1, 10);
}
else
{
Toast.makeText(getApplicationContext(), "You can not add more than 2 photos" , 1).show();
}
}
});
alertDialog.setNeutralButton("Gallery", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
if(Tree_Image.count<3)
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
getParent().startActivityForResult(Intent.createChooser(intent,"Select Picture"),1);
}
else
{
Toast.makeText(getApplicationContext(), "You can not add more than 2 photos" , 1).show();
}
}
});
alertDialog.setNegativeButton("View Selected Photos", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface arg0, int arg1)
{
Intent i = new Intent(getParent(),Show_Selected_Images.class);
//i.putExtra("cqname", client_name.getText().toString());
startActivity(i);
}
});
alertDialog.show();
}
});
这是我的onActivityResult方法： -
protected void onActivityResult(int requestCode, int resultcode, Intent intent)
{
int orientation =0;
Log.d("result ","code uis"+resultcode);
super.onActivityResult(requestCode, resultcode, intent);
if (requestCode == 1)
{
if (intent != null && resultcode == RESULT_OK)
{
Uri selectedImage = intent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
Log.v("log","filePath is : "+filePath);
cursor.close();
try
{
ExifInterface exif = new ExifInterface(filePath);
orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
//Toast.makeText(getApplicationContext(), ""+orientation, 1).show();
Log.v("log", "ort is "+orientation);
}
catch (IOException e)
{
e.printStackTrace();
}
if(bmp != null && !bmp.isRecycled())
{
bmp = null;
}
File f = new File(filePath);
bmp = decodeFile(f,400,400);
if (orientation==6)
{
Matrix matrix = new Matrix();
matrix.postRotate(90);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
}
else if (orientation==8)

}

}
Log.v("log", "before width is "+bmp.getWidth() + " and height is "+bmp.getHeight());
bt=Bitmap.createScaledBitmap(bmp,320, 300, false);
// Bitmap bt_thumb = Bitmap.createScaledBitmap(bmp, 70, 70, false);
Intent i = new Intent(Tree_Assessmnt_Tree.this,Tree_Image.class);
i.putExtra("userid", uid);
// TabGroupActivity parentActivity = (TabGroupActivity) getParent();
startActivity(i);

答案 0 :(得分：1)
其他做法就是这样。

答案 1 :(得分：0)
您正在startActivityForResult()
getParent()
尝试删除getParent()
