2022-01-21 界面长亮不熄屏

1.在AndroidManifest.xml文件中添加权限

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 {

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

        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    }
}
