Recyclerview is Scrolling when media Player is playing. How can i fix it?

I'm developing a ChatApp with the function of Audio Messages. The Recording and playing of this Audio Messages are working very well, but if i click on Play Button the Recyclerview is scrolling up. Anyone have an idea?
Sorry for my bad english, i'm from Germany ;)

Splash Screen Android - Count Down Timer Display

I am trying to use splash screen for my app.
I want to display Count down timer in my splash screen.
So far I am able to achieve the splash screen working but don't know how to display count down timer. I created layout for count down timer. I want splash screen to stay for 5 Hours then take to the next activity.
Splashactivity.java
public class splash_screen extends AppCompatActivity {
private float imageAplha = 1f;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
//splashScreenUseTimer(5000);
splashScreenUseAsyncTask();
}
// Show splash screen until network load data complete.
private void splashScreenUseAsyncTask()
{
// Create a AsyncTask object.
final RetrieveDateTask retrieveDateTask = new RetrieveDateTask();
retrieveDateTask.execute("", "", "");
// Get splash image view object.
final ImageView splashImageView = (ImageView) findViewById(R.id.logo_id);
// Create a count down timer object.It will count down every 0.1 seconds and last for milliSeconds milliseconds..
CountDownTimer countDownTimer = new CountDownTimer(5000, 100) {
#Override
public void onTick(long l) {
// Reduce the splash screen background image's alpha value for each count down.
splashImageView.setAlpha(imageAplha);
imageAplha -= 0.1;
if(imageAplha <= 0)
{
imageAplha = 1;
}
}
#Override
public void onFinish() {
// When count down complete, set the image to invisible.
imageAplha = 0;
splashImageView.setAlpha(imageAplha);
// If AsyncTask is not complete, restart the counter to count again.
if(!retrieveDateTask.isAsyncTaskComplete()) {
this.start();
}
}
};
// Start the count down timer.
countDownTimer.start();
}
// This is the async task class that get data from network.
private class RetrieveDateTask extends AsyncTask<String, String, String>{
// Indicate whether AsyncTask complete or not.
private boolean asyncTaskComplete = false;
public boolean isAsyncTaskComplete() {
return asyncTaskComplete;
}
public void setAsyncTaskComplete(boolean asyncTaskComplete) {
this.asyncTaskComplete = asyncTaskComplete;
}
// This method will be called before AsyncTask run.
#Override
protected void onPreExecute() {
this.asyncTaskComplete = false;
}
// This method will be called when AsyncTask run.
#Override
protected String doInBackground(String... strings) {
try {
// Simulate a network operation which will last for 10 seconds.
Thread currTread = Thread.currentThread();
for (int i = 0; i < 10; i++) {
currTread.sleep(1000);
}
}catch(Exception ex)
{
ex.printStackTrace();
}finally {
return null;
}
}
// This method will be called after AsyncTask run.
#Override
protected void onPostExecute(String s) {
// Start SplashScreenMainActivity.
Intent mainIntent = new Intent(splash_screen.this,
MainActivity.class);
splash_screen.this.startActivity(mainIntent);
// Close SplashScreenActivity.
splash_screen.this.finish();
this.asyncTaskComplete = true;
}

How to efficiently put a multitude of stopwatches on one activity?

I made a single working stopwatch, but I can't figure out a way to add several to the same page. What would be an effective way to do this? I tried copying the code and changing all the parameters but that did not seem to work.
The code I have at the moment:

Turn the stopwatch into either a custom view or fragment. Then you should only need to include the view/fragment in the xml, and call the appropriate event handler functions you added in the java code.

The timer not let the user to edit

I'm a begginer and i build a timer app and i want the app to allow the user to edit the time. like in the android build in timer. and i wrote the code and it not really works it's show like it can be edit but when i'm trying to write something, it's change for a sec and go back to what it's been before..

What do i need to fix?

The code below will give you a good idea of what to do. When you click the button, it will get the text of the EditText and put it into string. Then it will convert into int. Then you can put the new int variable time into your CountDownTimer function's 1st parameter to set the length of the timer.
Button submit;
TextView timerText;
EditText editTextTime;
CountdownTimer yourTimer;
String timeString;
int time;
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
timeString = String.valueOf(editTextTime.getText());
time = Integer.valueOf(timeString);
}
});
yourTimer = new CountDownTimer(time, 1000) {
#Override
public void onTick(long millisUntilFinished) {
int seconds = (int) millisUntilFinished / 1000;
int minutes = seconds / 60;
seconds %= 60;
minutes %= 60;
if (seconds < 10 && seconds >= 1) {
timerText.setText("" + seconds);
}
}
#Override
public void onFinish() {
}
}.start();

setMinimumHeight() on LinearLayout isn't working (in subclass)

I have a subclass of a liner layout (referenced from XML custom type) The minimum height I've tried to set just isn't working nor is setting the layout. I need to do this programatically...
Why isn't setMinimumHeight() working?
NB: The complexity of the code can be ignored, the value it is setting is 70
public class SummaryDynamicSpacer extends LinearLayout {
private static final String TAG = "mymeter-DynamicSpacer";
int dpWidth = 0;
int dpHeight = 0;
public SummaryDynamicSpacer(Context context) {
super(context);
init(context);
}
public SummaryDynamicSpacer(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
private void init(Context context) {
DisplayMetrics metrics = new DisplayMetrics();
((Activity)context).getWindowManager().getDefaultDisplay().getMetrics(metrics);
//Set dpWidth, this is the key metric we use for scaling.
float density = getResources().getDisplayMetrics().density;
float dpWidth = metrics.widthPixels / density;
float dpHeight = metrics.heightPixels / density;
this.dpWidth = (int)dpWidth;
this.dpHeight = (int)dpHeight;
Log.d(TAG, "zyxHeightDP: "+metrics.heightPixels / density);
int id = this.getId();
int increment = 10;
int adjustment = getValueForLargeDevice(increment);
if(id == R.id.betweenAddressAndTopBox) {
doBetweenAddressAndTopBox(context, adjustment);
} else if(id == R.id.betweenTopAndAddress) {
doBetweenTopAndAddress(context, adjustment);
}
Log.d(TAG, "SettingHeight: "+adjustment);
this.setBackgroundColor(Color.BLUE);
}
private void doBetweenAddressAndTopBox(Context context, int adjustment) {
this.setMinimumHeight(adjustment);
}
private void doBetweenTopAndAddress(Context context, int adjustment) {
this.setMinimumHeight(adjustment);
}
private int getValueForLargeDevice(double increment) {
int largeDeviceAdjustment = 0;
if(dpHeight > 750) {
int difference = (int)dpHeight - 750;
int interval = 25;
int iterations = (difference / interval) > 12 ? 12 : (difference / interval);
int increasePerInterval = 0;
for(int i=0; i < iterations; i++) {
largeDeviceAdjustment += increment;
}
return largeDeviceAdjustment;
} else {
return 1;
}
}
}

I think your code is fine. Your layout likely has an issue. Did you set the layout as follows?
<com.example.dynamicspacerlayout.SummaryDynamicSpacer
android:id="#+id/betweenAddressAndTopBox"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
See this also does minHeight do anything?

Hope that Helps!
