[英]How to save a picture in an application?
我想知道如何將圖像保存在存儲器中,因為在我的應用程序中我可以拍照並看到它,但是當我關閉應用程序並重新打開它時,該圖像消失了,我使用了位圖。
我的代碼:
public static final int REQUEST_CODE = 01;
private ImageView imgs1;
private File outputMediaFile;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.semana1);
imgs1 = (ImageView) findViewById(R.id.imgs1);
}
public void btnTakePhotoClicked1(View v){
Intent intent1= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent1, REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
Bitmap bm1= (Bitmap) data.getExtras().get("data");
imgs1.setImageBitmap(bm1);
}
}
獲取圖像位圖對象后,請在onActivityResult中使用此代碼。
File file = new File("foldername/imagename.jpg")
OutputStream fOut = new FileOutputStream(file);
bm1.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
