我的代码在这里工作正常。它会在某些时候更改我的库中的图像,但我不认为这是最好的方法,尤其是使用thread.sleep()。我怎样才能为此编写更好的代码?我错过了什么? 感谢..
@覆盖 protected void onResume(){ paraThread = true; workThread = new LooperFoto(“MyWorkThread”); workThread.setPriority(从Thread.MIN_PRIORITY); workThread.start(); super.onResume(); }
@Override
protected void onStop() {
Log.i(TAG, "thread state: " + workThread.getState());
paraThread = false;
workThread = null;
super.onStop();
}
class LooperFoto extends HandlerThread {
public LooperFoto(String name) {
super(name);
}
@Override
public void run() {
while (paraThread) {
try {
this.sleep(2000);
mudaFoto.sendMessage(new Message());
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
Handler mudaFoto = new Handler() {
public void handleMessage(Message msg) {
Random generator = new Random();
int randomIndex = generator.nextInt(thumbImgGallery.getAdapter()
.getCount());
thumbImgGallery.setSelection(randomIndex);
};
};

只要.sleeping()的线程不是你的主(UI)线程,你应该没问题。你在担心什么?
