Update TextView from TimerTask, Handler, schedule, run, cancel TimerTask, Android example
public class TimerActivity extends Activity {
TimerTask mTimerTask;
final Handler handler = new Handler();
Timer t = new Timer();
TextView hTextView;
TableRow hTableRow;
Button hButton, hButtonStop;
private int nCounter = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
hTextView = (TextView)findViewById(R.id.idTextView);
hButton = (Button)findViewById(R.id.idButton);
hButton.setOnClickListener(mButtonStartListener);
hButtonStop = (Button)findViewById(R.id.idButtonStop);
hButtonStop.setOnClickListener(mButtonStopListener);
} // end onCreate
View.OnClickListener mButtonStartListener = new OnClickListener() {
public void onClick(View v) {
doTimerTask();
}
};
View.OnClickListener mButtonStopListener = new OnClickListener() {
public void onClick(View v) {
stopTask();
}
};
public void doTimerTask(){
mTimerTask = new TimerTask() {
public void run() {
handler.post(new Runnable() {
public void run() {
nCounter++;
// update TextView
hTextView.setText("Timer: " + nCounter);
Log.d("TIMER", "TimerTask run");
}
});
}};
// public void schedule (TimerTask task, long delay, long period)
t.schedule(mTimerTask, 500, 3000); //
}
public void stopTask(){
if(mTimerTask!=null){
hTextView.setText("Timer canceled: " + nCounter);
Log.d("TIMER", "timer canceled");
mTimerTask.cancel();
}
}
}
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
TextView textView = new TextView(this);
textView.setText("Text View ");
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
layout.addView(textView, p);
Button buttonView = new Button(this);
buttonView.setText("Button");
buttonView.setOnClickListener(mThisButtonListener);
layout.addView(buttonView, p);
}
private OnClickListener mThisButtonListener = new OnClickListener() {
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Hello !",
Toast.LENGTH_LONG).show();
}
};

SeekBar setOnSeekBarChangeListener Example. Change TextView font size by SeekBar Example.
TextView mTextView01 = (TextView)findViewById(R.id.textView01);
SeekBar mSeekBarTexSize = (SeekBar)findViewById(R.id.seekBarTextSize);
mSeekBarTexSize.setMax(100);
mSeekBarTexSize.setProgress(25);
mSeekBarTexSize.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
mTextView01.setTextSize((float)progress);
}
public void onStartTrackingTouch(SeekBar seekBar) {}
public void onStopTrackingTouch(SeekBar seekBar) {}
});
