传递一个文本字符串到另一个活动的Andr​​oid工作室 [英] Passing a Text String to another activity Android studio

问题描述

public class Milk extends Activity {

private CountDownTimer countDownTimer;
private final long startTime = 1000 * 60 * 60 * 24 * 7;
private final long interval = 1 * 1000;
public TextView textView;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.timer);


    textView = (TextView) this.findViewById(R.id.milkTimer);
    countDownTimer = new CountDownTimerActivity(startTime, interval);
    textView.setText(textView.getText() + String.format("%02d:%02d:%02d", startTime / 3600,
            (startTime % 3600) / 60, (startTime % 60)));

    countDownTimer.start();

}

我有我的Milk.Java页面上这个倒数计时器。我想倒数计时器移动到我的

I have this Countdown timer on my Milk.Java page. I want to move the Countdown timer to my

Timer.Java页是

Timer.Java Page which is

public class Timer extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.timer);

    }

}

我如何code它，所以我的TextView传给我的计时器页面？

How can I code it so my textView is passed to my Timer page?

推荐答案

您可以从一个活动使用意图的数据传递到另一个活动。
请注明你的问题，如果这不是你要找的答案。

You can pass data from one activity to another activity using intents. Please specify your question if this is not the answer you were looking for.

Intent intent = new Intent(this, Timer.class);
intent.putExtra("EXTRA_TIMERDATA", textView.getText().toString());
startActivity(intent);
