Mostly we require to get an image from camera or gallery in our apps ,So here how to go about it :-
Tested this code on 5.1 android lolipop works fine hope this helps all :-)
1. CameraActivity.java
public class CameraActivity extends Activity {
Uri outputFileUri;
String selectedImagePath = "";
ImageView mUserImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
initiViews();
}
private void initiViews() {
mUserImage = (ImageView) findViewById(R.id.mUserImage);
mUserImage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
popmenu();
}
});
}
void popmenu() {
final Dialog dialog = new Dialog(CameraActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.cameradialog);
dialog.getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
Button mCamerabtn = (Button) dialog.findViewById(R.id.cameradialogbtn);
Button mGallerybtn = (Button) dialog
.findViewById(R.id.gallerydialogbtn);
Button btnCancel = (Button) dialog.findViewById(R.id.canceldialogbtn);
dialog.getWindow().setLayout(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);
mCamerabtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(),
"test.jpg");
outputFileUri = Uri.fromFile(file);
Log.d("TAG", "outputFileUri intent" + outputFileUri);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, 0);
dialog.cancel();
}
});
mGallerybtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 1);
dialog.cancel();
}
});
btnCancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.cancel(); // dismissing the popup
}
});
dialog.show();
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
