说明：
两种方法实现底部弹出的对话框：
推荐用DialogFragment
效果图：
布局文件dialog_select_call.xml：
<?xml version="1.0" encoding="utf-8"?>
Dialog实现源码：
初始化：
private void dialogSelectCallInit() {
dialogSelectCall = new Dialog(this, R.style.DialogPopBottom);
View inflate = LayoutInflater.from(this).inflate(R.layout.dialog_select_call, null);
dialogSelectCall.setContentView(inflate);
Window dialogWindow = dialogSelectCall.getWindow();
dialogWindow.setGravity(Gravity.BOTTOM);
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
lp.x = 0;
lp.y = 0;
lp.width = getResources().getDisplayMetrics().widthPixels;
dialogWindow.setAttributes(lp);
RelativeLayout layoutVoice = (RelativeLayout) inflate.findViewById(R.id.layout_voice);
RelativeLayout layoutVideo = (RelativeLayout) inflate.findViewById(R.id.layout_video);
Button buttonCancel = (Button) inflate.findViewById(R.id.cancel);
RxView.clicks(layoutVoice)
.throttleFirst(2, TimeUnit.SECONDS)
.compose(this.bindUntilEvent(ActivityEvent.DESTROY))
.subscribe(v -> {
// dialogSelectCall.cancel();
VoiceSessionActivity.startActivityCallOut(this, userId);
});
RxView.clicks(layoutVideo)
.throttleFirst(2, TimeUnit.SECONDS)
.compose(this.bindUntilEvent(ActivityEvent.DESTROY))
.subscribe(v -> {
// dialogSelectCall.cancel();
// VideoSessionActivity.startActivityCallOut(this, userId);
});
RxView.clicks(buttonCancel)
.throttleFirst(2, TimeUnit.SECONDS)
.compose(this.bindUntilEvent(ActivityEvent.DESTROY))
.subscribe(v -> dialogSelectCall.cancel());
RxView.touches(layoutVoice, motionEvent -> {
dealLayoutTouch(layoutVoice, motionEvent);
return false;
}).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {});
RxView.touches(layoutVideo, motionEvent -> {
dealLayoutTouch(layoutVideo, motionEvent);
return false;
}).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {});
}
private void dealLayoutTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
v.setBackgroundColor(Color.rgb(200, 200, 200));
break;
case MotionEvent.ACTION_UP:
v.setBackgroundColor(Color.WHITE);
break;
}
}
显示对话框：
dialogSelectCall.show()
DialogFragment实现源码：
定义了一个类SelectCallDialog.Java继承DialogFragment

显示对话框前初始化参数：
selectCallDialog.init(userId);
显示对话框后：
selectCallDialog.show(getFragmentManager(), "");
