[英]Unable to pick gallery image from Fragment
這是怎么回事?
我正在嘗試從圖庫中選擇一張照片,然后將該照片設置為我的ImageButton圖像。 這應該是非常直接的,但不知怎的,我搞砸了。 這就是我的嘗試:我有一個片段,我在其中設置我的標簽和我的ImageButton:
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
TabHost host = (TabHost)getView().findViewById(R.id.tabHost);
host.setup();
//Tab 1
TabHost.TabSpec spec = host.newTabSpec("Foto");
spec.setContent(R.id.tab1);
spec.setIndicator("Foto");
host.addTab(spec);
//Tab 2
spec = host.newTabSpec("Sentimento");
spec.setContent(R.id.tab2);
spec.setIndicator("sentimento");
host.addTab(spec);
//Tab 3
spec = host.newTabSpec("Medição");
spec.setContent(R.id.tab3);
spec.setIndicator("Medição");
host.addTab(spec);
cancelBtn = (ImageButton)getView().findViewById(R.id.cancel_post_btn);
saveBtn = (ImageButton)getView().findViewById(R.id.save_post_btn);
insertPostText = (EditText)getView().findViewById(R.id.insert_post_text);
postImageBtn = (ImageButton)getView().findViewById(R.id.post_img_btn);
postImageBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, GALLERY_REQUEST);
}
});
}
這是我的日志的onActivityResult方法:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("---------", "activity result");
if (requestCode == GALLERY_REQUEST && requestCode == getActivity().RESULT_OK){
Log.d("-----------", "result ok");
Uri imageUri = data.getData();
postImageBtn.setImageURI(imageUri);
} else {
Log.d("-----------", "result not ok");
Log.d("----------", String.valueOf(requestCode));
Log.d("----------", String.valueOf(RESULT_OK));
}
}
這些是我的日志結果:
03-07 14:23:50.767 30717-30717/? D/---------: activity result
03-07 14:23:50.767 30717-30717/? D/-----------: result not ok
03-07 14:23:50.767 30717-30717/? D/----------: 1
03-07 14:23:50.767 30717-30717/? D/----------: -1
最后這是我的android清單:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
你們有沒有想過為什么會這樣?
嘗試將您的圖庫意圖更改為:
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
if (isAdded() && pickPhoto.resolveActivity(getActivity().getPackageManager()) != null)
startActivityForResult(pickPhoto, requestCode);
其中使用了ContentProvider
樣式的機器
這讓我感到非常慚愧,但我仍然需要發布答案以防萬一有人達到這個問題。 我應該比較一下
getActivity().RESULT_OK
同
resultCode
所以這就是它現在的工作方式:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("---------", "activity result");
if (requestCode == GALLERY_REQUEST && resultCode == getActivity().RESULT_OK){
Log.d("-----------", "result ok");
Uri imageUri = data.getData();
postImageBtn.setImageURI(imageUri);
} else {
Log.d("-----------", "result not ok");
Log.d("----------", String.valueOf(requestCode));
Log.d("----------", String.valueOf(RESULT_OK));
}
}
