Question

我想将android studio天文钟的时间保存在可在应用程序内部访问的txt文件中。（例如，单击“保存”按钮，天文钟表的值将保存在txt文件中（以后可访问））

代码中的

BTW，如果可能的话，它还具有一个内置计数器，可以将allong与txt文件保存在一起，而该文件将是AWESOME。只是不确定如何做

这里是我的代码MainActivity.java

public class MainActivity extends AppCompatActivity {
private Chronometer chronometer;
private long pauseOffset;
private boolean running;
private int mCounter = 0;
private Button button;
Button btn;
TextView txv;
TextView txtv;

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


    chronometer = findViewById(R.id.chronometer);


    btn = (Button) findViewById(R.id.bt);
    txv = (TextView) findViewById(R.id.tx);



    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mCounter++;
            txv.setText(Integer.toString(mCounter));

            button = (Button) findViewById(R.id.PreviousRuns);
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    openRunHistory();
                }

            });
        }

    });
}


public void startChronometer(View v) {
    if (!running) {
        chronometer.setBase(SystemClock.elapsedRealtime() - pauseOffset);
        chronometer.start();
        running = true;
    }

}

public void pauseChronometer(View v) {
    if (running) {
        chronometer.stop();
        pauseOffset = SystemClock.elapsedRealtime() - chronometer.getBase();
        running = false;
    }

}

public void resetChronometer(View v) {
    chronometer.setBase(SystemClock.elapsedRealtime());
    pauseOffset = 0;
    txv.setText("0");
    mCounter = 0;
    txtv.setText("");

}

public void openRunHistory() {
    Intent intent = new Intent(this, RunHistory.class);
    startActivity(intent);


}

这是您必须在onClick的保存按钮上实现的代码，“ data”是带有时间的字符串

SetConsoleCP

}

节省计时器的时间？
