问题描述
我有一个 TextView ，我想每5秒用我的String中的每个字符串更新 TextView 数组。
I have a TextView and I would like to update the TextView every 5 second with each string in my String Array.
这是我尝试的代码。
TextView display;
EditText caption;
Thread thread;
String blinks;
String[] wc;
private CountDownTimer timer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
display = (TextView) findViewById(R.id.display);
caption = (EditText) findViewById(R.id.caption);
timer = new CountDownTimer(5000, 20) {
@Override
public void onTick(long millisUntilFinished) {
String[] wc = {"The","Qucik", "Brown","fox","Jumped"};
for (int j = 0; j < wc.length; j++) {
blinks = wc[j];
final String[] titles = {"" + blinks + ""};
for (int i = 0; i < titles.length; i++) {
display.setText(titles[i]);
}
}
}
@Override
public void onFinish() {
try{
yourMethod();
}catch(Exception e){
}
}
}.start();
}
推荐答案
final String[] wc = {"The", "Qucik", "Brown", "fox", "Jumped"};
final android.os.Handler handler = new android.os.Handler();
handler.post(new Runnable() {
int i = 0;
@Override
public void run() {
display.setText(wc[i]);
i++;
if (i == wc.length) {
handler.removeCallbacks(this);
} else {
//5 sec
handler.postDelayed(this, 1000 * 5);
}
}
});
