我有一個小問題。如何在onTick（）方法中的多個TextView中設置文本
new CountDownTimer(12000, 2000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
}
}.start();
在這裏我setText至6不同TextView（在一個XML）與每個onTick()喜歡。任何想法我可以做到這一點？由於
//編輯
I would like have something like this
First tick
tv.setText("one")
Second Tick
tv2.setText("two")
嘗試使用TextViews的陣列狀
TextView[] textViews = new TextView[6];
String[] value = new String[]{"one","two","three","four","five","six"};
int count = 0;
new CountDownTimer(12000, 2000) {
public void onTick(long millisUntilFinished) {
textViews[count].setText(value[count]);// you can set dynamic string variable also
count++;
}
public void onFinish() {
}
}.start();
這就是我正在尋找。謝謝 ;） – djmloody27
檢查下面的答案，
new CountDownTimer(12000, 2000) {
public void onTick(long millisUntilFinished) {
Activity_Name.this.runOnUiThread(new Runnable() {
@Override
public void run() {
tv1.setText("");
tv2.setText("");
tv3.setText("");
tv4.setText("");
}
});
}
public void onFinish() {
}
}.start();
我想setText每個滴答一次。在每個下一個滴答聲中，我都會將setText設置爲其他TextView。任何選項？ – djmloody27
採取一個int變量，並增加onTick方法和使用開關或如果在textview設置值 – Vickyexpert
你可以做這樣的事情：
new CountDownTimer(12000, 2000) {
int counter = 0;
public void onTick(long millisUntilFinished) {
switch (counter) {
case 0:
tv1.setText("");
break;
case 1:
tv2.setText("");
break;
// ...
}
counter++;
}
public void onFinish() {
}
}.start();
