Android Java中的Sleep() [英] Sleep() in Android Java
问题描述
我正在关注本教程在我的电脑中有一个加载屏幕程序.该教程说,我的活动应该使用Sleep()命令进行Sleep()操作,但是它无法将Sleep()识别为函数,并向我提供了一个错误,询问我是否要创建一个称为Sleep()的方法. >
这是代码示例:
public class LoadingScreenActivity extends Activity {
//Introduce an delay
private final int WAIT_TIME = 2500;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
System.out.println("LoadingScreenActivity screen started");
setContentView(R.layout.loading_screen);
findViewById(R.id.mainSpinner1).setVisibility(View.VISIBLE);
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
//Simulating a long running task
this.Sleep(1000);
System.out.println("Going to Profile Data");
/* Create an Intent that will start the ProfileData-Activity. */
Intent mainIntent = new Intent(LoadingScreenActivity.this,ProfileData.class);
LoadingScreenActivity.this.startActivity(mainIntent);
LoadingScreenActivity.this.finish();
}
}, WAIT_TIME);
}
}
您可以使用以下方法之一:
Thread.sleep(timeInMills);
或
SystemClock.sleep(timeInMills);
SystemClock.sleep(milliseconds)
是非常类似于Thread.sleep(milliseconds)
的实用程序功能,但是它忽略了InterruptedException
.如果您不使用Thread.interrupt()
,请使用此函数进行延迟,因为它将保留线程的中断状态.
I am following this tutorial to have a loading screen in my program. The tutorial says my activity should Sleep() using the Sleep() command, however it does not recognize Sleep() as a function and provides me with an error, asking if I would like to create a method called Sleep().
Here is the code sample:
public class LoadingScreenActivity extends Activity {
//Introduce an delay
private final int WAIT_TIME = 2500;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
System.out.println("LoadingScreenActivity screen started");
setContentView(R.layout.loading_screen);
findViewById(R.id.mainSpinner1).setVisibility(View.VISIBLE);
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
//Simulating a long running task
this.Sleep(1000);
System.out.println("Going to Profile Data");
/* Create an Intent that will start the ProfileData-Activity. */
Intent mainIntent = new Intent(LoadingScreenActivity.this,ProfileData.class);
LoadingScreenActivity.this.startActivity(mainIntent);
LoadingScreenActivity.this.finish();
}
}, WAIT_TIME);
}
}
You can use one of the folllowing methods:
Thread.sleep(timeInMills);
or
SystemClock.sleep(timeInMills);
SystemClock.sleep(milliseconds)
is a utility function very similar to Thread.sleep(milliseconds)
, but it ignores InterruptedException
. Use this function for delays if you do not use Thread.interrupt()
, as it will preserve the interrupted state of the thread.
