您应该使用Timer类来启动新活动。我相信您希望实现一个延迟几秒的屏幕,然后启动主应用程序。就像主应用程序启动前的启动屏幕一样,对吗 那么这将帮助你
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/** set time to splash out */
final int welcomeScreenDisplay = 4000;
/** create a thread to show splash up to splash time */
Thread welcomeThread = new Thread() {
int wait = 0;
@Override
public void run() {
try {
super.run();
/**
* use while to get the splash time. Use sleep() to increase
* the wait variable for every 100L.

while (wait < welcomeScreenDisplay) {
sleep(100);
wait += 100;

} catch (Exception e) {
System.out.println("EXc=" + e);

/**

创建时的公共void(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/**设定泼水的时间*/
最终屏幕显示=4000;
/**创建一个线程以显示从启动到启动时间的启动*/
线程welcomeThread=新线程(){
int wait=0;

while(等待
这是一个延迟4秒的屏幕
