Android保持屏幕常亮，PowerManager.WakeLock的使用
package com.hebaijun.wakelock;
import android.app.Activity;
import android.os.Bundle;
import android.os.PowerManager;
public class WakeLockActivity extends Activity {
PowerManager.WakeLock wakeLock;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wakeLock = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ON_AFTER_RELEASE,
"WakeLockActivity");
}
@Override
protected void onPause() {
super.onPause();
if (wakeLock != null) {
wakeLock.release();
}
}
@Override
protected void onResume() {
super.onResume();
wakeLock.acquire();
}
}
需要在AndroidManifest.xml中添加权限
<uses-permission android:name="android.permission.WAKE_LOCK"/>
