我正在嘗試使用Android的內置圖庫。我能夠獲得畫廊和相冊,但是無論何時我想要顯示圖像,畫廊都會直接將我引導回我的應用程序。儘管已被調用,但我無法查看圖像。Android - 圖像不會從內置圖庫中顯示
這是我的代碼:
public class CameraTab extends Activity implements OnClickListener{
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera_tab);
ImageButton cameraBtn = (ImageButton)findViewById(R.id.camera_btn);
cameraBtn.setOnClickListener(this);
ImageButton galleryBtn = (ImageButton)findViewById(R.id.gallery_btn);
galleryBtn.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == this.findViewById(R.id.camera_btn)){
/// some codes here
}
if (v == this.findViewById(R.id.gallery_btn)){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
任何人都可以幫我嗎?任何幫助,將不勝感激!!謝謝!!
