退出应用工具类
import java.util.Stack;
import android.app.Activity;
import android.app.ActivityManager;
import android.content.Context;
public class AppManager {
private static Stack<Activity> activityStack;
private static AppManager instance;
private AppManager(){}
/**
* 单一实例
*/
public static AppManager getAppManager(){
if(instance==null){
instance=new AppManager();
}
return instance;
}
/**
* 添加Activity到堆栈
*/
public void addActivity(Activity activity){
if(activityStack==null){
activityStack=new Stack<Activity>();
}
activityStack.add(activity);
}
/**
* 获取当前Activity(堆栈中最后一个压入的)
*/
public Activity currentActivity(){
Activity activity=activityStack.lastElement();
return activity;
}
/**
* 结束当前Activity(堆栈中最后一个压入的)
*/
public void finishActivity(){
Activity activity=activityStack.lastElement();
finishActivity(activity);
}
/**
* 结束指定的Activity
*/
public void finishActivity(Activity activity){
if(activity!=null){
activityStack.remove(activity);
activity.finish();
activity=null;
}
}
/**
* 结束指定类名的Activity
*/
public void finishActivity(Class<?> cls){
for (Activity activity : activityStack) {
if(activity.getClass().equals(cls) ){
finishActivity(activity);
}
}
}
/**
* 结束所有Activity
*/
public void finishAllActivity(){
for (int i = 0, size = activityStack.size(); i < size; i++){
if (null != activityStack.get(i)){
activityStack.get(i).finish();
}
}
activityStack.clear();
}
/**
* 退出应用程序
*/
public void AppExit(Context context) {
try {
finishAllActivity();
ActivityManager activityMgr= (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
activityMgr.restartPackage(context.getPackageName());
System.exit(0);
} catch (Exception e) { }
}
}
然后再每个应用的onCreate()方法中添加如下:
addActivityintoStack();
将Activity加入栈中的方法:
private void addActivityintoStack() {
BaseApp app = (BaseApp)getApplication();
app.getAppManager().addActivity(this);
}
