I've been looking for information on Google for 2 days. But all
without results.
I want to use not the full screen mode, but the reduced one, so that
you can scan a certain area.
In Api Google, I also did not find what I needed.
The variant with resizing in SurfaceView is attached with a picture.
As you can see, the result is deplorable ((.
Is there a solution to my problem?

Today i am posting my first question here in stackoverflow.
My app's subject is speech to text application all the app is working but the text doen't appear in its zone after saying the speech. So i am here asking you all for help.
Belong my xml file :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

So please again and thank you all for your time.
I have created a flashlight fragment for my app and I have implemented this code and turning the flashlight on works, but I can't turn it off.
I tried to switch the light on and off from one button or like now from two but it made no difference.
When I switch the fragment, the light turns off.
I hope anyone knows what to do.
Thx

Try to off the light using the below code:
cam.stopPreview();
cam.release(); // Very Important line
In which line?
private void turnOffLight() {

if (camera == null || parameters == null) {
return;
}
camera = Camera.open();

parameters.setFlashMode(Camera.Parameters.FLASH_MODE_OFF);

camera.stopPreview();
camera.release(); // Very Important line
lightIsOn = false;
button_OnOff.setText("On");
}
}

Here is what gets displayed when the app is ran on my phone:
I was able to fix the issue by using a FrameLayout instead of a SurfaceView
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/camera_view">
</FrameLayout>
AdMob view is not visible, but clickable. If call onResume() view become visible. When I use
AdMob library all work fine, but if use google play services for AdMob I got this issue.
My code is bellow.
protected void initAdMob(){
if (mAdView == null) {
mAdView = new AdView(MainActivity.this);
mAdView.setAdUnitId(getString(R.string.admob_id));
mAdView.setAdSize(AdSize.SMART_BANNER);
mAdView.loadAd(new AdRequest.Builder().build());
mAdView.setAdListener(new AdListener() {
#Override
public void onAdClosed() {
super.onAdClosed();
}
#Override
public void onAdFailedToLoad(int errorCode) {
super.onAdFailedToLoad(errorCode);
}
#Override
public void onAdLeftApplication() {
super.onAdLeftApplication();
}
#Override
public void onAdOpened() {
super.onAdOpened();
}
#Override
public void onAdLoaded() {
super.onAdLoaded();
}
});
}
}
private void showAdMob() {
initAdMob();
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams( FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER_HORIZONTAL;
mAdView.setLayoutParams(params);
FrameLayout fl = (FrameLayout) mainView.findViewById(R.id.adView);
if (fl != null) {
fl.removeAllViews();
fl.addView(mAdView, params);
}
}
#Override
public void onResume() {
if(mAdView != null){
mAdView.resume();
}
super.onResume();
}
view xml:
<FrameLayout
android:id="#+id/gameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<FrameLayout
android:id="#+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
Need to use Mediation ID instead Publisher ID in AdMob
