(1) xml控件:
android:id="@+id/mTextView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
(2)Activity:
private CountDownTimerstart;
start =new CountDownTimer(6000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
mTextView.setText("跳转" +"(" + millisUntilFinished /1000 +"秒" +")");
}
@Override
public void onFinish() {
startActivity(new Intent(WelcomeActivity2.this, WelcomeActivity3.class));
}
}.start();
}
防止二次跳转
start.cancel();
