In my project , I want to play the sound and user must guess the sound.
every thing works well.
I have grid that show some letters and user must selected correct letters to make the right word.
when user selected letters my button fill from left to right
my language is persian and filling my button must be from right to left.
here is my code but don't know where I do this change.

here I CREATE place to fill by selected letter by user:

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]));
}
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

I am writing a simple application to scan and record WiFi Access Points, there are three options; a single scan, 10 scans, or scan for a period of time.
When I enter my nWiFiScans activity it preforms the scans, records the file and STARTS THE ACTIVITY AGAIN!!!
WHY WOULD IT DO THIS???

I ran it, removed the file creation and the Intent(You only need to call finish();) and then it worked. Have you checked that it actually goes through File creation for you? Because mine got stuck there and then it jumps out of try so it can't reach the finish(); call, I also called unregisterReceiver(receiverWifi); before finish();
EDIT, File creation:
File sdCard = Environment.getExternalStorageDirectory(); //returns sdcard directory
File dir = new File (sdCard.getAbsolutePath() + "/mydirectory");
dir.mkdirs();
File file = new File(dir, "filename");
I'm trying to implement a CountDownTimer in an Android Application. This timer will, while running, countdown from a value, than reset, than countdown from a different value. Switching back and force between values until either a set number of rounds have elapsed or the stop button has been pressed. I can get the CountDownTimer samples to work, but I guess I'm missing something here. Below is the applicable button press code;
CounterState state = CounterState.WORKOUT;
private WorkoutTimer workoutTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {

switch(v.getId()) {
case R.id.start_button:
if (!timer_running) {
timer_running = true;
Log.d(TAG, "clicked on Start Button");
// If the state is unknown, set it to Workout first
int State = state.getStateValue();
if (State == 0) {
state.setStateValue(1);
}
workoutTimer.start();
}
break;
case R.id.stop_button:
Log.d(TAG, "clicked on Stop Button");
if (timer_running); {
timer_running = false;
workoutTimer.cancel();
}
break;
private class WorkoutTimer extends CountDownTimer{
public WorkoutTimer(long interval) {
super(getThisTime(), interval);
Log.d(TAG, "WorkoutTimer Constructed...");
}
TextView digital_display = (TextView) findViewById(R.id.digital_display);

public void onFinish() {
int State = state.getStateValue();
int roundsLeft = 0;
if (State == 1) {
state.setStateValue(2);
} else {
state.setStateValue(1);
}
decrementRounds();
try {
roundsLeft = Integer.parseInt(numOfRounds.getText().toString());
} catch(NumberFormatException nfe) {
roundsLeft = 999;
}
if (roundsLeft > 0 || roundsLeft != 999) {
workoutTimer.start();
}
}
public void onTick(long millisUntilFinished) {

final long seconds_left = (millisUntilFinished / 1000) - (minutes_left * 60);
final long millis_left = millisUntilFinished % 100;
String time_left = String.format("%02d:%02d.d", minutes_left, seconds_left,
millis_left);
digital_display.setText(time_left);
}
}
private long getThisTime() {
long time = 0;
TextView workout_time = (TextView) findViewById(R.id.workout_time);
TextView rest_time = (TextView) findViewById(R.id.rest_time);
switch(state) {
case WORKOUT:
try {
time = Integer.parseInt(workout_time.getText().toString());
} catch(NumberFormatException nfe) {
time = 999;
}
// time = 90;
Log.d(TAG, "Workout time = " + time);
break;
case REST:
try {
time = Integer.parseInt(rest_time.getText().toString());
} catch(NumberFormatException nfe) {
time = 999;
}
// time = 30;
Log.d(TAG, "Rest time = " + time);
break;
case UNKNOWN:
time = 0;
break;
}
return time;
}
Everything starts up okay, but crashes when I click either button. If I comment out my calls to the workoutTimer, no crash. I never see my log in the constructor of the workoutTimer class, so obviously I'm missing something here. Any help would be appreciated.

You have not initialized your workoutTimer. You need to add the following line in your onCreate method.
workoutTimer = new WorkoutTimer(...);

so how to repaint my chart? i hope somebody can show me where is my fault, and tell me the way to fix it
Use chartView.removeView(Graphical_View)
before setting the chart view with new values, followed by use the 'Graphical_View.repaint()' inorder to set new value to the layout
However use multirenderer.setInScroll(true);
Hard to understand the question, but I will try to guess.
In order to repaint the chart, you need to call chartView.repaint();
However, the issue you have may be fixed by having an mRenderer.setInScroll(true); call.
I slove this problem using this code
if(layout != null)
layout.removeAllViews();
layout.addView(mChartView, new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
mChartView = null;
