Android: Error trying to edit button text after thread sleep
- by Vass
(programming Android in Eclipse) I am trying to set up a delay in changing the text in a button. I am getting errors only after there is a delay and the text needs to be changed. Here is the simplified code without a while loop:
final Button button_target = (Button) findViewById(R.id.button_target);
Thread textChange = new Thread(new Runnable() {
public void run(){
button_target.setText("fog");
try{
Thread.sleep(3000);
}catch(InterruptedException e){}
}
});
textChange.start();
And now here is the code where a change of text on the button is required after the sleep which now causes and error and exit (forced):
final Button button_target = (Button) findViewById(R.id.button_target);
Thread textChange = new Thread(new Runnable() {
public void run(){
button_target.setText("cat");
try{
Thread.sleep(3000);
}catch(InterruptedException e){}
button_target.setText("dog");
}
});
textChange.start();
what am I doing to cause the error? Is there another method that I should do to be able to invoke a sleep or delay to the thread so that a text change operation can be performed?
(the actual code has a while loop but I believe this form puts the error in highlight)
