Cannot resolve showQueston argument in getActivity().showQuestion inside my Fragment

I'm using activity class code to create a fragment of each. I was able to successfully change the Mainactivity class to main fragment with replacing this with getActivity() and adding view before each findmyID.
But I'm not able to convert showquestion which highlights in red color although I added getActivity() before it replacing Mainactivity.this which was before.
Here is the screenshot
Here is the whole code

Any help is well appreciated. Thanks in advance.

getActivity() returns Activity. So cast it before use.
((YourActivity) getActivity()).showQuestion(...);
Make sure showQuestion() method is public in YourActivity.

here I CREATE place to fill by selected letter by user:
private void createWord(int length) {
LinearLayout world_layout = (LinearLayout) findViewById(R.id.world_layout);
LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, length);
word_btn = new Button[length];
for (int i = 0; i < length; i++) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}
}
and here i check the letters to fill:
private void createResult() {
resultWord = "";
for (int i = 0; i < word_array.length; i++) {
if (word_btn[i].getText() != "") {
resultWord +=word_btn[i].getText();
}
}
if (resultWord.length() == word_array.length) {
if (resultWord.equalsIgnoreCase(theWord)) {
showMyDialog(1, null);
} else {
showMyDialog(2, null);
}
}
}
now it works but my button fill from left to right
I want to fill right to left

Try adding android:supportsRtl="true" in <application> in your AndroidManifest.xml, and then android:layoutDirection="rtl" in your root layout.

Using a check if the language is right to left from this answer, I would structure your code like this:
private static boolean isRTL() {
final int directionality = Character.getDirectionality(Locale.getDefault().getDisplayName().charAt(0));
return directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT ||
directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT_ARABIC;
}
private void populateButtons(int i, Button word_btn) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}
private void createWord(int length) {
LinearLayout world_layout = (LinearLayout) findViewById(R.id.world_layout);
LayoutParams param = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, length);
word_btn = new Button[length];
if(isRTL()) {
for(int j = length - 1; j >= 0; j--) {
populateButtons(j, word_btn);
}
} else {}
for (int k = 0; k < length; k++) {
populateButtons(k, word_btn)
}
}

After 2 days, I found the solution. It was easy as a piece of cake.
I dont know why I make it so compilacated.
I just change the my if clause like this:
for (int i = length -1; i >= 0; i--) {
word_btn[i] = new Button(getApplicationContext());
word_btn[i].setText("");
word_btn[i].setId(i);
word_btn[i].setTextColor(Color.parseColor("#ffffff"));
word_btn[i].setTextSize(24);
word_btn[i].setTypeface(Typeface.DEFAULT_BOLD);
word_btn[i].setLayoutParams(param);
word_btn[i].setBackgroundResource(R.drawable.matchbox);
world_layout.addView(word_btn[i]);
word_btn[i].setOnClickListener(charOnClick(word_btn[i]));
}

Sharing Intent Not working Properly

I have one quote application. I have implemented share and copy function in it. I am facing issue is that I am not getting shared first time sharing quote. Means if there 50 quote in list and if I try to share any quote from list than it is not sharing anything. after that if I move on another quote and try to sharing than its working fine. I have same issue in copy function also. I also face some time issue like if I share quote number 50 than its sharing another number quote. Please help me for solve the bug. Thanks

Android CountDown Timer won't stop [closed]

Closed 9 years ago.
Ok so here is my problem. I am working on a trivia game that uses a question counter to display 10 questions and once that happens it calls the finalscore class. I have implemented a timer that resets for every question and if time runs up it proceeds to the next question. However if nothing is clicked on the final question it will keep looping back to the finalscore class even after starting a new game.
public class game extends Activity implements OnClickListener {
// int[] anArray;
int[] anArray2 = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

mCountdown is never null so change your code
void cancelTimer() {
if (mCountDown != null) {
mCountDown.cancel();
