【中文标题】在 TabHost 中 onActivityResult 不起作用【英文标题】：In TabHost onActivityResult is not working 【发布时间】：2012-10-28 12:53:52 【问题描述】：我有一个 TabHost，并且在这 4 个不同的活动中。在第一个选项卡中，我可以选择从图库中选择图像或从相机拍照。现在，我使用了 public void onActivityResult(int requestCode, int resultcode, Intent intent) 方法..但是，它没有在 TabHost 中被调用..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..在此先感谢..
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)
Matrix matrix = new Matrix();
matrix.postRotate(270);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
else if (orientation==3)
Matrix matrix = new Matrix();
matrix.postRotate(180);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
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);
else
Log.v("log", "Photopicker canceled");
else if (requestCode == 10)
File out = new File(Environment.getExternalStorageDirectory(), "newImage.jpg");
if(!out.exists())
Log.v("log", "file not found");
Toast.makeText(getBaseContext(),"Error while capturing image", Toast.LENGTH_LONG).show();
return;
Log.v("log", "file "+out.getAbsolutePath());
File f = new File(out.getAbsolutePath());
try
ExifInterface exif = new ExifInterface(out.getAbsolutePath());
orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
//Toast.makeText(getApplicationContext(), ""+orientation, 1).show();
Log.v("log", "ort is "+orientation);
catch (IOException e)
e.printStackTrace();
Bitmap photo =decodeFile(f,400,400);
if (orientation==6)
Matrix matrix = new Matrix();
matrix.postRotate(90);
photo = Bitmap.createBitmap(photo, 0, 0, photo.getWidth(), photo.getHeight(), matrix, true);
else if (orientation==8)
Matrix matrix = new Matrix();
matrix.postRotate(270);
photo = Bitmap.createBitmap(photo, 0, 0, photo.getWidth(), photo.getHeight(), matrix, true);
else if (orientation==3)
Matrix matrix = new Matrix();
matrix.postRotate(180);
photo = Bitmap.createBitmap(photo, 0, 0, photo.getWidth(), photo.getHeight(), matrix, true);
//Bitmap photo = (Bitmap) intent.getExtras().get("data");
//bt=Bitmap.createScaledBitmap(photo, 380, 520, false);
bt=photo;
// bt=Bitmap.createScaledBitmap(photo,320, 300, false);
// Log.v("log", "before width is "+bt.getWidth() + " and height is "+bt.getHeight());
/* gamePic.setBackgroundResource(0);
gamePic.setImageBitmap(photo);*/
//txtPhoto.setText(""+DrawOnImage_Activity.count);
Intent i = new Intent(Tree_Assessmnt_Tree.this,Tree_Image.class);
i.putExtra("userid", uid);
startActivity(i);
else if(requestCode==6)
if (intent == null)
Log.v("log", "Null data, but RESULT_OK, from image picker!");
Toast t = Toast.makeText(this, "No Photo Slected",Toast.LENGTH_SHORT);
t.show();
return;
【问题讨论】：
你在哪里设置你的 onClickListener 和你的 onActivityResult ？在您的 TabHost 或 Activity 中？ 为什么要使用 getParent() 方法？改用当前活动，其中定义了 onActivityResult() 方法。 我从 ***.com/questions/10777154/… 链接显示这个。但仍然无法正常工作 我删除了 getParent() 但它仍然无法正常工作 实际上onActivityResult方法没有被调用 【参考方案1】：其他的做法是这样的。
-
单击按钮（您要打开 Intent）打开另一个活动。
在另一个活动的 onCreate() 上打开该意图。
onActivityResult 设置上一个活动的静态数据并调用finish()。
这样就不会有人知道你打开了这样一个活动并且你会得到你的数据。

【讨论】：
感谢您的回复..它正在工作...但是打开画廊比正常时间需要一些时间【参考方案2】：你在getParent()上打电话给startActivityForResult()
尝试删除getParent()
