Android 自定义PopWindow完整代码

1.布局文件的编写

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/comment_item_linear"
    android:layout_width="380dp"

        android:text="回复"
        android:textColor="@color/white" />

    <TextView
        android:layout_width="1dp"

        android:layout_height="match_parent"
        android:layout_weight="1"
        android:drawableTop="@mipmap/icon_comment_copy"
        android:gravity="center"
        android:paddingBottom="20dp"
        android:paddingTop="15dp"
        android:text="复制"
        android:textColor="@color/white" />

    <TextView
        android:layout_width="1dp"
        android:layout_height="match_parent"
        android:layout_gravity="center_vertical"
        android:layout_marginBottom="20dp"
        android:layout_marginTop="15dp"

        android:paddingTop="15dp"
        android:text="举报"
        android:textColor="@color/white" />
</LinearLayout>

2.自定义PopWindow代码部分

package com.bookuu.bookuulibrary.ui.view;

import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.TextView;

import com.bookuu.bookuulibrary.R;
import com.bookuu.bookuulibrary.config.MyApp;

/**

 * 复制/回复/评论/举报功能
 */

public class CommtentPopWindow extends PopupWindow implements View.OnClickListener {
    private View conentView;
    private LinearLayout comment_item_linear;
    private TextView tv_comment_share;
    private TextView tv_comment_pinlun;
    private TextView tv_comment_copy;
    private TextView tv_comment_report;
    View mPopView;

    private OnItemClickListener mListener;

    public CommtentPopWindow(final Context context) {
        super(context);

        initView(context);
        setPopupWindow();
        tv_comment_share.setOnClickListener(this);
        tv_comment_pinlun.setOnClickListener(this);
        tv_comment_share.setOnClickListener(this);
        tv_comment_copy.setOnClickListener(this);
        tv_comment_report.setOnClickListener(this);
    }

    private void initView(Context context) {

        LayoutInflater inflater = LayoutInflater.from(context);
        mPopView = inflater.inflate(R.layout.popurwindow_item_comment, null);

        comment_item_linear = (LinearLayout) mPopView.findViewById(R.id.comment_item_linear);
        tv_comment_share = (TextView) mPopView.findViewById(R.id.tv_comment_share);
        tv_comment_pinlun = (TextView) mPopView.findViewById(R.id.tv_comment_pinlun);
        tv_comment_copy = (TextView) mPopView.findViewById(R.id.tv_comment_copy);
        tv_comment_report = (TextView) mPopView.findViewById(R.id.tv_comment_report);

        comment_item_linear.setOnClickListener(this);
        tv_comment_share.setOnClickListener(this);
        tv_comment_copy.setOnClickListener(this);
        tv_comment_pinlun.setOnClickListener(this);
        tv_comment_report.setOnClickListener(this);
    }

    private void setPopupWindow() {
        this.setContentView(mPopView);// 设置View
        this.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);// 设置弹出窗口的宽
        this.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);// 设置弹出窗口的高
        this.setFocusable(true);// 设置弹出窗口可
        this.setAnimationStyle(R.style.mypopwindow_anim_style);// 设置动画
        this.setBackgroundDrawable(new ColorDrawable(0x00000000));// 设置背景透明
        mPopView.setOnTouchListener(new View.OnTouchListener() {// 如果触摸位置在窗口外面则销毁

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-generated method stub
//                int height = mPopView.findViewById(R.id.id_pop_layout).getTop();
//                int y = (int) event.getY();
//                if (event.getAction() == MotionEvent.ACTION_UP) {
//                    if (y < height) {
//                        dismiss();
//                    }
//                }

                MyApp.getApp().showToast("ontouch....");
                return true;
            }
        });
    }

    /**
     * 显示popupWindow
     *
     * @param parent
     */
    public void showPopupWindow(View parent) {
        if (!this.isShowing()) {
            // 以下拉方式显示popupwindow

//            this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);
        } else {
            this.dismiss();
        }
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if (mListener != null) {
            mListener.setOnItemClick(v);
        }
    }

    /**
     * 定义一个接口，公布出去 在Activity中操作按钮的单击事件
     */
    public interface OnItemClickListener {
        void setOnItemClick(View v);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        this.mListener = listener;
    }

}

3.在调用的地方如何使用

mPop = new CommtentPopWindow(context);
mPop.setOnItemClickListener(this);

实现

CommtentPopWindow.OnItemClickListener接口在

setOnItemClick方法中做想做的功能即可

        @Override
        public void setOnItemClick(View v) {

            switch (v.getId()) {
                case R.id.comment_item_linear:

//                MyApp.getApp().showToast("lin");
                    break;

                case R.id.tv_comment_share:

                    MyApp.getApp().showToast("分享.....");

                    break;
                case R.id.tv_comment_pinlun:
                    MyApp.getApp().showToast("评论.....");

                    break;
                case R.id.tv_comment_copy:
//                    String text;
//                    ClipboardManager clipboardManager = (ClipboardManager) mContext.getSystemService(Context.CLIPBOARD_SERVICE);
//                    clipboardManager.setPrimaryClip(ClipData.newPlainText(text, comment_content));

                    MyApp.getApp().showToast("  复制.....");

                    break;
                case R.id.tv_comment_report:

                    MyApp.getApp().showToast("举报.....");

                    break;
            }
        }
