Handle#removeCallbacks 在stackoverflow上找了相关资料Why to use removeCallbacks() with postDelayed()?...这次我们使用自定Handler进行removeCallBacks和postDelayed，完美的解决了问题。 下面记录一下整问题解决过程中的思考~！...Handle的removeCallBacks移除方法是不可靠的么？...换句话说，Handle#removeCallBacks移除的就是在队列中等待被执行的Message。 那么问题到底出在哪里，而且为什么postDelayed替换为post问题的复现概率降低了？...= null) { attachInfo.mHandler.removeCallbacks(action); attachInfo.mViewRootImpl.mChoreographer.removeCallbacks

SystemClock.uptimeMillis(); if (mBlink == null) mBlink = new Blink(); mTextView.removeCallbacks...= null) mTextView.removeCallbacks(mBlink); } } Blink实现了Runnable接口，对应的代码如下： static final int... run() { if (mCancelled) { return; } mTextView.removeCallbacks...mCancelled) { mTextView.removeCallbacks(this); mCancelled = true;

直接看代码说来的明白些： 1.在activity中定义一个Handler对象 private Handler handler; 2.初始化 handler = new Handler(); 3.使用 handler.removeCallbacks...position); overlay.setText(sections[position]); overlay.setVisibility(View.VISIBLE); handler.removeCallbacks...1.5秒后执行，让overlay为不可见 handler.postDelayed(overlayThread, 1500); } } } 这里要说道了：postDelayed方法和removeCallbacks...方法removeCallbacks方法是删除指定的Runnable对象，使线程对象停止运行：首先我们为什么要让这个线程停止运行呢？...position); overlay.setText(sections[position]); overlay.setVisibility(View.VISIBLE); handler.removeCallbacks
例1： private Runnable mNextRunnable = new Runnable() { @Override public void run() { mHandler.removeCallbacks...mExecutor.shutdownNow(); } 2.消息对象从消息队列移除 如果你的Handler是被delay的Message持有了引用，那么使用相应的Handler的removeCallbacks.../** *删除消息队列中任何待处理的Runnable */ public final void removeCallbacks(Runnable r) {...= null) { mHandler.removeCallbacks(null); } } 方法二：将Handler声明为静态类，activity使用弱引用赋值进去
ServerRefresh implements Runnable { @Override public void run() { timerHandler .removeCallbacks
mTextView.setText(mTexts[index++]); mHandler.postDelayed(mRunnable, 1000); } } } 0x19 removeCallbacks...方法 比如这里有个定时更新TextView的文本的代码，如果想要按下按钮，停止定时更换文本，就可以通过removeCallbacks方法，传入该Runnable来中止消息。...mBtnRemove = findViewById(R.id.mBtnRemove); mBtnRemove.setOnClickListener(v -> mHandler.removeCallbacks
= null) { handler.removeCallbacks(hideRunnable); handler.postDelayed
使用post,postDelayed 添加委托，使用 removeCallbacks移除委托。 由上面的特性我们可以简单看出“handler类似一个容器对象，它携带了消息的集合和委托的集合”。...setOnClickListener(new OnClickListener(){ public void onClick(View v) { //移除回调 _handler.removeCallbacks
position); overlay.setText(sections[position]); overlay.setVisibility(View.VISIBLE); handler.removeCallbacks...overlay.setText(sections[position]);//设置我们自定义的吐司的文本 overlay.setVisibility(View.VISIBLE);//设置吐司的可见 handler.removeCallbacks
end.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v){ handler.removeCallbacks
