我有片段A和B.A包含一個列表，B包含一個imageview。當我在碎片中的列表項點擊進入B.我是從B.片段在活動結果調用後關閉
呼叫相機和畫廊意圖在B中onActivityResult B中
alert.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if (item == 0) {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, PICK_FROM_CAMERA);
} else if (item == 1) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, PICK_FROM_FILE);
} else {
dialog.cancel();
}
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_FROM_CAMERA) {
if (resultCode == getActivity().RESULT_OK) {
bitmap = (Bitmap) data.getExtras().get("data");
cameraIcon.setImageBitmap(bitmap);
} else if (resultCode == getActivity().RESULT_CANCELED) {
Toast.makeText(getActivity(), "Result has been cancelled!",
Toast.LENGTH_LONG).show();
}
} else if (requestCode == PICK_FROM_FILE) {
try {
if (resultCode == getActivity().RESULT_OK) {
try {
stream = getActivity().getContentResolver()
.openInputStream(data.getData());
} catch (FileNotFoundException e) {
e.printStackTrace();
}
bitmap = BitmapFactory.decodeStream(stream);
cameraIcon
.setImageBitmap(Bitmap.createScaledBitmap(bitmap,
bitmap.getWidth()/2,
bitmap.getHeight()/2, true));
} else if (resultCode == getActivity().RESULT_CANCELED) {
Toast.makeText(getActivity(), "Result has been cancelled!",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
}
}
}
但在意圖收集圖像之後的某些時間並且來到onActivityResult片段B 被關閉並且進入片段A而不是將圖像設置爲片段B中的圖像視圖.....
我在做什麼錯請幫忙
準確地說luttu !!這是問題..它適用於其他設備很好....非常感謝您的時間.... –
那麼，成功的android開發的關鍵是知道這些問題，並知道如何繞過它們。將不需要的行爲歸咎於「其他設備」的結果可能是許多「其他設備」的所有者將僅僅拒絕您的應用。 – Bondax
