我每 6 秒后使用处理程序调用特定方法。
代码：
tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(),"Logout" , Toast.LENGTH_LONG).show();
}
});
final Handler handler=new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
UpdateTask();
handler.postDelayed(this, 6000);
}
}, 1000);
现在的问题是，当我单击 textview tv （这让我吐司“注销”）时，当消息要读取时（或者当控件处于 UpdateTask() 方法中时，它会在 6 秒后单击注销。
无论代码在 UpdateTask() 方法中，我只想随时点击 textview“tv”。
我怎样才能做到这一点？
请帮忙。
