The Settings.Systemprovider offers a SCREEN_OFF_TIMEOUTsetting that might be what you are looking for.

public class HelloWorld extends Activity
{
private static final int DELAY = 3000;
int defTimeOut = 0;
@Override
protected void onCreate(Bundle savedInstanceState)
{
// Be sure to call the super class.
super.onCreate(savedInstanceState);
// See assets/res/any/layout/hello_world.xml for this
// view layout definition, which is being set here as
// the content of our screen.
setContentView(R.layout.hello_world);
defTimeOut = Settings.System.getInt(getContentResolver(),
Settings.System.SCREEN_OFF_TIMEOUT, DELAY);
Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, DELAY);
}
@Override
protected void onDestroy()
{
super.onDestroy();
Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, defTimeOut);
}
}
And also dont forget to add this permission in manifest:
并且不要忘记在清单中添加此权限：
android:name="android.permission.WRITE_SETTINGS"

Above is correct:
以上是正确的：
Settings.System.putInt(getContentResolver(),Settings.System.SCREEN_OFF_TIMEOUT, DELAY);
But also include permission in manifest:
但也包括清单中的许可：
android:name="android.permission.WRITE_SETTINGS"

Here is a code-sheet, you can do more.
这是一个代码表，你可以做更多。
long stand = Settings.System.getLong(
mContext.getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT,
-1);
long sec = stand / 1000;
String time = null;
if(stand<0) {
//close.
}
else if( sec >= 60) {//to minute
time = String.format(mContext.getString(R.string.minutes), (sec / 60) + "");
} else {
time = String.format( mContext.getString(R.string.seconds),sec + "");
}
