直播平台搭建，计时和倒计时功能的分别实现

一、计时功能：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    tools:context=".ChronometerActivity">
    <Chronometer
        android:id="@+id/chronometer"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:gravity="center"/>
</LinearLayout>
public class ChronometerActivity extends AppCompatActivity {
    private static final String TAG = "ChronometerActivity";
    private Chronometer chronometer;
    int count=60;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chronometer);
        chronometer=(Chronometer)findViewById(R.id.chronometer);
        chronometer.start();
        //停止计时
        //chronometer.stop();
       
    }
}

​

二、倒计时功能：

public class ChronometerActivity extends AppCompatActivity {
    private static final String TAG = "ChronometerActivity";
    private Chronometer chronometer;
    int count = 60;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chronometer);
        chronometer = (Chronometer) findViewById(R.id.chronometer);
        chronometer.start();
        //停止计时
        //chronometer.stop();
        chronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
            @Override
            public void onChronometerTick(Chronometer chronometer) {
                count--;
                chronometer.setText(count + "");
                if (count == 0) {
                    chronometer.stop();
                }
            }
        });
    }
}
