EditText not focusing, and not showing keyboard after keyboard is hidden after one input

I am implementing an OTP Verification system and have 3 EditText fields in my layout, and one of them is hidden until the user clicks a button.
Here is the layout file:

The problem I am having is that when the third otp EditText is shown it doesn't show the virtual keyboard or gets focused when clicked. Instead I have to first click one of the previous two EditTexts for it to show the virtual keyboard.
What can I do to make the virtual keyboard show on clicking the OTP field at once?
Here is the java file.

otpField.animate().alpha(1f).setDuration(500);
verifyOTP.setVisibility(View.VISIBLE);

}
};
}
}

Put this line when you want to give it focus:
otpField.requestFocus();
Also, to show the soft keyboard explicitly, you can do like below:
otpField.postDelayed(new Runnable() {
#Override
public void run() {
InputMethodManager im = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
im.showSoftInput(otpField, InputMethodManager.SHOW_IMPLICIT);
}
},200);

onclick listener not working in surfaceview of swipe layout

I am trying to call constructor on onClick listener of getSurfaceView for swipe layout but it is not happening.
RideAdapter.java
#Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View view;
if (viewType == RIDE_ITEM_TYPE) {
view = inflater.inflate(R.layout.item_upcoming_share_ride, parent, false);
swipeLayout = (SwipeLayout) view.findViewById(R.id.sample2);
swipeLayout.setShowMode(SwipeLayout.ShowMode.LayDown);
swipeLayout.addDrag(SwipeLayout.DragEdge.Right, swipeLayout.findViewWithTag("Bottom2"));
// sample2.setShowMode(SwipeLayout.ShowMode.PullOut);
swipeLayout.findViewById(R.id.edit).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "Star", Toast.LENGTH_SHORT).show();
}
});`
swipeLayout.findViewById(R.id.delete).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "Magnifier", Toast.LENGTH_SHORT).show();
}
});
swipeLayout.getSurfaceView().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v = inflater.inflate(R.layout.item_upcoming_share_ride, parent, false);
new OfferedRideCardViewHolder(v);
}
});
return new OfferedRideCardViewHolder(view);

Toast is working but constructor is not doing anything

I've tried a lot of different things that I found on the internet but nothing works.
Could someone help me in how to fix this problem and show me where I've gone wrong?

You have added the click functionality in xml. In that case you don't have to attach the click listener to the button. Listener implementation is required only if you haven't added the click functionality in xml. Use either of the approach, not both together.
Solution 1
Change
imgButton.setOnClickListener(new View.OnClickListener() {
public void onClickFavBtn(View v) {
boolean isFavourite = readState();
if (isFavourite) {
imgButton.setBackgroundResource(R.drawable.staroff);
isFavourite = false;
saveState(isFavourite);
} else {
imgButton.setBackgroundResource(R.drawable.staron);
isFavourite = true;
saveState(isFavourite);
}
}
});
to (just remove the listener attaching part)
public void onClickFavBtn(View v) {
boolean isFavourite = readState();
if (isFavourite) {
imgButton.setBackgroundResource(R.drawable.staroff);
isFavourite = false;
saveState(isFavourite);
} else {
imgButton.setBackgroundResource(R.drawable.staron);
isFavourite = true;
saveState(isFavourite);
}
}
Solution 2
Remove android:onClick="onClickFavBtn" from xml and
Change
public void onClickFavBtn(View v) {
to
public void onClick(View v) {

EDIT:
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;
public class FavouriteBtn extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.recipe);
final ImageButton imgButton = (ImageButton) findViewById(R.id.favbtn);
imgButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean isFavourite = readState();
if (isFavourite) {
imgButton.setImageResource(R.drawable.staroff);
saveState(false);
} else {
imgButton.setImageResource(R.drawable.staron);
saveState(true);
}
}
});
}
private void saveState(boolean isFavourite) {
SharedPreferences aSharedPreferences = this.getSharedPreferences(
"Favourite", Context.MODE_PRIVATE);
SharedPreferences.Editor aSharedPreferencesEdit = aSharedPreferences
.edit();
aSharedPreferencesEdit.putBoolean("State", isFavourite);
aSharedPreferencesEdit.commit();
}
private boolean readState() {
SharedPreferences aSharedPreferences = this.getSharedPreferences(
"Favourite", Context.MODE_PRIVATE);
return aSharedPreferences.getBoolean("State", true);
}
}
Simply remove:
android:onClick="onClickFavBtn"
from your XML ImageButton
and change onClickFavBtn to onClick in listener.

You need to handle onClick of the button in this manner and show a toast if the edittext is empty
if(editText.getText().toString().trim().length()==0){
Toast.makeText(getApplicationContext(), "field is empty",
Toast.LENGTH_LONG).show();
}else{
//your code here
}

If you want to check for empty EditText.. try TextUtils for it.
Example
if (TextUtils.isEmpty(edtText.getText().toString().trim())) {
Toast.makeText(getBaseContext(),
"Empty", Toast.LENGTH_SHORT)
.show();
} else {
Toast.makeText(getBaseContext(),
"Not Empty", Toast.LENGTH_SHORT)
.show();
}

How do i exit runnable and switch another activity

I have a textview timer, i want it stops after 10 seconds of showing on display and after 10 seconds that my current activity jumps to an other activity
Runnable runnable = new Runnable()
{
#Override
public void run()
{
while(Running)
{
try{
Thread.sleep(1000);
}catch(InterruptedException e)
{
e.printStackTrace();
}
handler.post(new Runnable()
{
#Override
public void run()
{
number+=1;
tvTimer.setText(String.valueOf(number)); //With setting value of number on textfield ITS POSSIBLE TO SEE THE TIMER
if(number==10)
{
Running = false;
handler.removeCallbacks(this);//that does not works for me to stop
Intent i = new Intent(getApplicationContext(), SonucMenu.class);
startActivity(i); //Starting my second class
}
}
});
}
}
My Second activity starts but the layout from second activity comes more than one time, what i want is that it comes only one time, and i think this problem depends on that i cant stop runnable

I think for this you can use following code , It worked for me.
It will start your activity after 10 seconds.
new Handler().postDelay(new Runnable() {
#Override
public void run() {
Start Your activity here.
}
}, 10000);
but one of the best solution will be (I just found it from develoer site):
new CountDownTimer(10000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
strat your activity here.
}
}.start();

Use View.post(Runnable) and View.postDelayed(Runnable, long), no need to create additional thread.
private TextView tvTimer;
private final Runnable mCountDownRunnable = new Runnable() {
private int mCount = 0;
#Override
public void run() {
mCount++;
if (mCount < 10) {
tvTimer.setText(Integer.toString(mCount));
tvTimer.postDelayed(this, 1000);
} else {
Intent i = new Intent(YourActivity.this, SonucMenu.class);
YourActivity.this.startActivity(i);
}
}
};
to start runnable, call tvTimer.post(mCountDownRunnable);
