仿微信右上角点击加号弹出PopupWindow

一。要弹出的布局，随便设计

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/my_phone">


    <TextView
        android:id="@+id/complain_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginTop="@dimen/sky_dp_size_10"
        android:layout_marginLeft="10dp"
        android:gravity="center"
        android:text="投诉"
        android:layout_marginRight="10dp"
        android:textColor="@android:color/black"
        android:textSize="18sp" />
    <TextView
        android:id="@+id/expect_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="@dimen/sky_dp_size_10"
        android:gravity="center"
        android:text="屏蔽"
        android:layout_marginRight="10dp"
        android:textColor="@android:color/black"
        android:textSize="18sp" />
LinearLayout>

二。自定义Popubwindow继承Popubwindow

public class PopWinShare extends PopupWindow {
    private View mainView;
    private TextView layoutShare, layoutCopy;

    public PopWinShare(Activity paramActivity, View.OnClickListener paramOnClickListener, int paramInt1, int paramInt2) {
        super(paramActivity);
        //窗口布局
        mainView = LayoutInflater.from(paramActivity).inflate(R.layout.popwin_share, null);
        //分享布局
        layoutShare = ((TextView) mainView.findViewById(R.id.complain_tv));
        //复制布局
        layoutCopy = (TextView) mainView.findViewById(R.id.expect_tv);
        //设置每个子布局的事件监听器
        if (paramOnClickListener != null) {
            layoutShare.setOnClickListener(paramOnClickListener);
            layoutCopy.setOnClickListener(paramOnClickListener);
        }
        setContentView(mainView);
        //设置宽度
        setWidth(paramInt1);
        //设置高度
        setHeight(paramInt2);
        //设置显示隐藏动画
        setAnimationStyle(R.style.AnimTools);
        //设置背景透明
        setBackgroundDrawable(new ColorDrawable(0));
    }

}

三。弹出动画样式

<style name="AnimTools" parent="@android:style/Animation">
    <item name="android:windowEnterAnimation">@anim/push_initem>
    <item name="android:windowExitAnimation">@anim/push_outitem>
style>

（1）新建anim文件新建push_in和push_out

<scale xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXScale="1.0"
    android:toXScale="1.0"
    android:fromYScale="0"
    android:toYScale="1.0"
    android:pivotX="0"
    android:pivotY="10%"
    android:duration="200" >

scale>

<scale xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXScale="1.0"
    android:toXScale="1.0"
    android:fromYScale="1.0"
    android:toYScale="0"
    android:pivotX="0"
    android:pivotY="10%"
    android:duration="200" >

scale>

四。使用

 if (popWinShare == null) {
                    //自定义的单击事件
                    OnClickLintener paramOnClickListener = new OnClickLintener();
                    popWinShare = new PopWinShare(PersonalHomepageActivity.this, paramOnClickListener, 120, 130);
                    //监听窗口的焦点事件，点击窗口外面则取消显示
                    popWinShare.getContentView().setOnFocusChangeListener(new View.OnFocusChangeListener() {

                        @Override
                        public void onFocusChange(View v, boolean hasFocus) {
                            if (!hasFocus) {
                                popWinShare.dismiss();
                            }
                        }
                    });
                }
//设置默认获取焦点
                popWinShare.setFocusable(true);
//以某个控件的x和y的偏移量位置开始显示窗口
                popWinShare.showAsDropDown(tousuTv, 0, 0);
//如果窗口存在，则更新
                popWinShare.update();

（1）按钮的点击事件

class OnClickLintener implements View.OnClickListener {

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.complain_tv:
                Intent intent = new Intent(PersonalHomepageActivity.this, ComplainActivity.class);
                intent.putExtra("about_user_id", friend_id);
                startActivity(intent);
                break;
            case R.id.expect_tv:
                getExpect();
                break;

            default:
                break;
        }

    }

}
