So i want to save the RelativeLayout (360x360dp) into the phone as a picture.
Here is the code that i found online, and on stackoverflow but it does not work.
Using api 24.

public class MainActivity extends AppCompatActivity {
EditText caption;
TextView captionTv;
Button savebtn;
RelativeLayout image;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image = findViewById(R.id.image);
caption = findViewById(R.id.caption);
captionTv = findViewById(R.id.captionTV);
savebtn = findViewById(R.id.savebtn);
caption.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
captionTv.setText(s);
}
});
savebtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Called", Toast.LENGTH_SHORT).show();
saveImage();
}
});
}
public void saveImage()
{
Bitmap bitmap;
bitmap= viewToBitmap(image);
saveImageToExternalStorage(bitmap);
// try {
// FileOutputStream output = new FileOutputStream(Environment.getExternalStorageDirectory() + "/path/to/file.png");
// bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
// output.close();
// } catch (FileNotFoundException e) {
// e.printStackTrace();
// } catch (IOException e) {
// e.printStackTrace();
// }
}
private void saveImageToExternalStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}
public Bitmap viewToBitmap(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}
}
Yes, i have in my androidmanifest.
