最近遇到一个需求,下面记录下实现方法 以及遇到的一些坑
需求如下:当app在后台时 收到push消息用系统的Notification进行通知;当app在前台时 收到push后采用
自定义风格弹出通知
效果如下:
第一种情况这里不探究 第二种情况这里采用PopWindow实现
步骤:
一 、实现自定义PopWindow类
class="java">
public class TuyaPopWindow extends PopupWindow {
private Activity mContext;
private View view;
//private ImageView iv_icon;
private TextView tv_title;
private TextView tv_content;
private Handler mHandler;
public TuyaPopWindow(View contentView, final Activity mContext) {
super(contentView, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT, true);
this.view = contentView;
this.mContext = mContext;
L.d("huohuo", "mContext:" + mContext);
mHandler = new Handler(mContext.getMainLooper());
//this.iv_icon= (ImageView) contentView.findViewById(R.id.iv_push_icon);
this.tv_title = (TextView) contentView.findViewById(R.id.tv_push_title);
this.tv_content = (TextView) contentView.findViewById(R.id.tv_push_msg);
tv_title.setText("设备:客厅插座");
tv_content.setText("xxxxx");
// 设置外部可点击
// mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框
this.view.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
//int height = view.findViewById(R.id.pop_layout).getTop();
// int y = (int) event.getY();
if (event.getAction() == MotionEvent.ACTION_UP) {
//if (y < height) {
dismiss();
//}
}
return true;
}
});
this.setFocusable(false);
this.setTouchable(true);
this.setOutsideTouchable(false);
this.update();
// 实例化一个ColorDrawable颜色为半透明
this.setBackgroundDrawable(new BitmapDrawable()); // 设置弹出窗体的背景
this.setAnimationStyle(R.style.take_photo_anim);
this.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
}
public void show() {
mHandler.post(new Runnable() {
@Override
public void run() {
//适配8.0系统
TuyaPopWindow.this.showAtLocation((mContext.findViewById(android.R.id.content)), Gravity.NO_GRAVITY, 0, 0);
//TuyaPopWindow.this.showAsDropDown(view, 0, 0);
}
});
//2s 消失
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
TuyaPopWindow.this.dismiss();
}
}, 2000);
}
}
二 、 定义PopWindow弹出位置
TuyaPopWindow.this.showAtLocation((mContext.findViewById(android.R.id.content)), Gravity.NO_GRAVITY, 0, 0);
这里要注意的是不要用这个方法,因为在8.0系统上这样会显示在布局底部,具体原因待探究
TuyaPopWindow.this.showAsDropDown(view, 0, 0);
还有一点在设置popupWindow属性的时候 需要执行设置这个属性
this.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
因为在4.0系统上会把状态栏算入布局中 这样会导致popupWindow覆盖掉状态栏
三、定义PopWindow 弹出动画
通过设置PopWindow的属性来实现
this.setAnimationStyle(R.style.take_photo_anim);
这里要用到的是style属性
首先我们需要声明 进入和离开的动画
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="500"
android:fromYDelta="-100%"
android:toYDelta="0" />
<alpha
android:duration="500"
android:fromAlpha="0.5"
android:toAlpha="1.0" />
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="500"
android:fromYDelta="0"
android:toYDelta="-100%" />
<alpha
android:duration="500"
android:fromAlpha="1.0"
android:toAlpha="0.5" />
</set>
申明style
<style name="take_photo_anim" parent="android:Animation">
<item name="android:windowEnterAnimation">@anim/pop_enter_anim</item>
<item name="android:windowExitAnimation">@anim/pop_exit_anim</item>
</style>
四、由于PopupWindow是依赖于Activity的,所以我们需要记录前台Activity
public class Constant {
//前台 activity 栈
private static LinkedList<Activity> foreActivityStack = new LinkedList<>();
public static void attachForeActivity(Activity activity) {
if (foreActivityStack.indexOf(activity) == -1) foreActivityStack.push(activity);
//Log.e("huohuo","attachForeActivity size:"+foreActivityStack.size()+" push:"+activity);
}
public static void detachForeActivity(Activity activity) {
foreActivityStack.remove(activity);
//foreActivityStack.pop();
//Log.e("huohuo","detachForeActivity size:"+foreActivityStack.size()+" pop:"+activity);
}
public static Activity getForeActivity(){
if(foreActivityStack.isEmpty())
return null;
//return foreActivityStack.peek().get();
return foreActivityStack.peek();
}
}
我们在每个Activity的onStart() onStop()方法中都调用
Constant.attachForeActivity(this);
Constant.detachForeActivity(this);
五、调用
if (Constant.getForeActivity() != null) {
//应用在前台
L.d(TAG, "getForeActivity true");
View contentView = LayoutInflater.from(Constant.getForeActivity()).inflate(R.layout.push_custom_layout, null);
TuyaPopWindow popWindow = new TuyaPopWindow(contentView,Constant.getForeActivity(), notify);
popWindow.show();
}
