android手机定时切换飞行模式代码(二)

这个类主要就是时间到了,自动切换了。

Log.d(AirPlaneModeActivity.TAG, "start state:" + startState);
Log.d(AirPlaneModeActivity.TAG, "end state:" + endState);
if (startState == 1)
{
Log.d(AirPlaneModeActivity.TAG, "set the fly mode true");
setAirPlaneState(true);
}
if (endState == 1)
{
Log.d(AirPlaneModeActivity.TAG, "set the fly mode false");
setAirPlaneState(false);
}
}
public void setAirPlaneState(boolean state)
{

if (state
&& System.getString(cr, System.AIRPLANE_MODE_ON)
.equals("0"))
{
Toast.makeText(context, "正在转飞行模式", Toast.LENGTH_LONG).show();
// 在receiver中10S没有处理 就会异常。
/* 本来想切换前,给用户点提示,可以取消啥滴。不然用户正在用,直接给切换了不爽啊。
* try { Log.e("tl3shi", "befor sleep"); Thread.sleep(5*1000);
