這裏是我的MainActivity.java如何將圖像設置爲圖庫中的圖像？請告訴我如何實現它？由於提前
public class MainActivity extends AppCompatActivity {
int PICK_IMAGE_REQUEST=1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn= (Button) findViewById(R.id.btnImgGet);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==RESULT_OK){
if(requestCode==PICK_IMAGE_REQUEST && null != data)
{
//Toast.makeText(getApplicationContext(),"onActivityResult working",Toast.LENGTH_SHORT).show();
try {
Uri uri = data.getData();
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri,projection,null,null,null);
cursor.moveToFirst();
int column_index=cursor.getColumnIndex(projection[0]);
String path = getString(column_index);
cursor.close();
// Log.d("Image Path is->",path);
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(path));
}catch (NullPointerException ex){ex.printStackTrace();}
}
}
}
}
這裏是logcat的..
