问题
I want to hide TextView after some time interval say 3 seconds. I googled and found some code and I tried code as shown below but It is not working.
Please tell me what is the wrong with this ?
tvRQPoint.setText("+0");
tvRQPoint.postDelayed(new Runnable() {
public void run() {
tvRQPoint.setText("+0");
}
}, 3000);
One more thing, how to remove timeout ? As I am using this on click event of ListView, If user clicks on one option and then clicks on second option, then as 3 seconds got over (after clicked on first option), It does not show second option for 3 seconds.
回答1:
try View INVISIBLE or GONE like:
tvRQPoint.postDelayed(new Runnable() {
public void run() {
tvRQPoint.setVisibility(View.INVISIBLE);
}
}, 3000);
Set View visibility with view.setVisibility(View.INVISIBLE|View.VISIBLE|View.GONE);

How about hiding your text view with some animation?
int delayMillis = 3000;
Handler handler = new Handler();
final View v = tvRQPoint; // your view
handler.postDelayed(new Runnable() {
@Override
public void run() {
TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);
animate.setDuration(500);
animate.setFillAfter(true);
v.startAnimation(animate);
v.setVisibility(View.GONE);
}, delayMillis);

What you are trying to do is ok but after three seconds you want to hide the textview so use setVisibility
tvRQPoint.setText("+0");
tvRQPoint.postDelayed(new Runnable() {
public void run() {
tvRQPoint.setVisibility(View.INVISIBLE);
}
}, 3000);

Try this-
Handler handler;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start);
tvRQPoint.setText("+0");
handler = new Handler();
handler.postDelayed(csRunnable, 3000);
}
Runnable csRunnable =new Runnable()
{
@Override
public void run()
{
tvRQPoint.setVisibility(View.INVISIBLE);
}
};

try this...
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView tv=(TextView)findViewById(R.id.tv);
tv.setText("+0");
tv.postDelayed(new Runnable() {
public void run() {
tv.setVisibility(View.INVISIBLE);
}
}, 3000);
}
}

You are setting the text in run() method. you can hide the text in two ways
View.INVISIBLE - give the space for the textview and hide its content
View.GONE - remove the space for textview and hide its content
so call
tvRQPoint.setVisibility(View.INVISIBLE);
(or)
tvRQPoint.setVisibility(View.GONE);

hope it's work:
tvRQPoint.setText("+0");
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
tvRQPoint.setVisibility(View.GONE);
}
},3000);
