1.在AndroidManifest.xml文件中添加权限

<uses-permission android:name="android.permission.WAKE_LOCK" />

2.在Activity的onCreate()函数中添加请求不熄屏的代码： getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

package org.venus.wd;import android.os.Bundle;
import android.view.WindowManager;import androidx.appcompat.app.AppCompatActivity;public class MainActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);}
}
