我是菜鸟，在android TV开发中遇到问题，记录下来，监听android 中的长按事件一般要执行 onKeyDown，onKeyLongPress，onKeyUp这三个方法。
private static double DOUBLE_CLICK_TIME = 0L;
private boolean isLongPressKey ;
private boolean lockLongPressKey;//判断长按还是
private boolean isDoublePressKey;//判断是否快速点击
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode){
case KeyEvent.KEYCODE_DPAD_DOWN:
if (event.getRepeatCount() == 0) {
event.startTracking();
isLongPressKey=false;
if((System.currentTimeMillis() - DOUBLE_CLICK_TIME)>600){
isDoublePressKey=false;
}else{
isDoublePressKey=true;
}
DOUBLE_CLICK_TIME = System.currentTimeMillis();
return true;
}else{
isLongPressKey=true;
return true;
}
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
switch (keyCode){
case KeyEvent.KEYCODE_DPAD_DOWN:
lockLongPressKey = true;
return true;
}
return super.onKeyDown(keyCode, event);
}
int mKeyTimes=0;//用来按下的上下键长按执行的次数
int mKeyRunTimes=0;
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if(event.getAction()==KeyEvent.ACTION_UP && isDoublePressKey){
mKeyTimes++;
}
switch (keyCode){
case KeyEvent.KEYCODE_DPAD_DOWN:
if(lockLongPressKey){
Log.d("xiaowu","isLongPressKey,444 "+event.getRepeatCount()+ "=="+isLongPressKey);
// TODO: 2017/6/11 加载数据
isLongPressKey=false;
lockLongPressKey=false;
}else{
if(!isLongPressKey ){
if(isDoublePressKey){
//任务延时加载
}else{
// TODO: 2017/6/11 加载数据
}
}
Log.d("xiaowu","isLongPressKey,333 "+event.getRepeatCount()+ "=="+isLongPressKey);
}
return true;
}
return super.onKeyUp(keyCode, event);
}
