相对应对话空,我觉得popupwindow更具有优势.(个人观点哈哈)

一:这里我对弹出pop做了简单的两个封装,显示一个按钮的,和显示两个按钮的

1,显示一个按钮的pop,的XML文件先贴效果图
这里写图片描述

这个是一个按钮的XML布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/btn_white_30"
    android:orientation="vertical">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical">


        <TextView
            android:id="@+id/tv_one_bt_content"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="@dimen/padding_10"
            android:gravity="center"
            android:text="请先对订单进行评价"
            android:layout_marginTop="@dimen/padding_20"
            android:layout_marginBottom="@dimen/padding_30"
            style="@style/Font_Middle_Gray" />

    </LinearLayout>

    <View style="@style/Style_hLine" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">


        <TextView
            android:id="@+id/tv_one_bt_ok"
            android:layout_width="@dimen/padding_0"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="确定"
            android:gravity="center"
            android:padding="@dimen/padding_10"
            style="@style/Font_Middle_Blue" />

    </LinearLayout>


</LinearLayout>

2,现在在写一个按钮的pop,以后使用的时候直接new我这个对象就可以了,

package com.lzyc.ybtappcal.widget.popupwindow;

import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.PopupWindow;
import android.widget.TextView;

import com.lzyc.ybtappcal.R;
import com.lzyc.ybtappcal.util.DensityUtils;
import com.lzyc.ybtappcal.util.ScreenUtils;
import com.lzyc.ybtappcal.util.Util;

/**

 * 备注：popupwindow
 */
public class PopupWindowOneButton extends PopupWindow {

    private Activity mContext;
    private TextView tv_content;
    private TextView tv_ok;

    public TextView getTv_content() {
        return tv_content;
    }

    public void setTv_content(TextView tv_content) {
        this.tv_content = tv_content;
    }

    public TextView getTv_ok() {
        return tv_ok;
    }

    public void setTv_ok(TextView tv_ok) {
        this.tv_ok = tv_ok;
    }

    public PopupWindowOneButton(Activity context) {
        this.mContext = context;
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View conentView = inflater.inflate(R.layout.popup_one_button, null);
        tv_content = (TextView) conentView.findViewById(R.id.tv_one_bt_content);
        tv_ok = (TextView) conentView.findViewById(R.id.tv_one_bt_ok);
        int h = context.getWindowManager().getDefaultDisplay().getHeight();
        int w = ScreenUtils.getScreenWidth() - DensityUtils.dp2px(60);  //ScreenUtils   DensityUtils 获取屏幕和转换dp的工具类
        // 设置SelectPicPopupWindow的View
        this.setContentView(conentView);
        // 设置SelectPicPopupWindow弹出窗体的宽
        this.setWidth(w);
        // 设置SelectPicPopupWindow弹出窗体的高
        this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
        // 设置SelectPicPopupWindow弹出窗体可点击
        this.setFocusable(true);
        this.setOutsideTouchable(true);
        // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作
        this.setBackgroundDrawable(new BitmapDrawable());
        // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
        // 设置SelectPicPopupWindow弹出窗体动画效果
    }


    /**
     * 显示popupWindow
     *
     * @param parent
     */
    public void showPopupWindow(View parent, int gravity) {
        if (!this.isShowing()) {
            // 以下拉方式显示popupwindow
            Util.setBackgroundAlpha(mContext, 0.5f);
            this.showAtLocation(parent, gravity, 0, 0);
        } else {
            this.dismiss();
        }

    }

    @Override
    public void dismiss() {
        super.dismiss();
        Util.setBackgroundAlpha(mContext, 1f);
    }
}

2,显示两个按钮的pop,就像对话框一样,看效果图
这里写图片描述

1,先贴XML布局代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/btn_white_30"
    android:orientation="vertical">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tv_two_bt_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="提示"
            android:layout_marginTop="@dimen/padding_10"
            style="@style/Font_Big_Black" />

        <TextView
            android:id="@+id/tv_two_bt_content"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="@dimen/padding_10"
            android:gravity="center"
            android:text="请先对订单进行评价"
            android:layout_marginTop="@dimen/padding_20"
            android:layout_marginBottom="@dimen/padding_30"
            style="@style/Font_Middle_Gray" />

    </LinearLayout>

    <View style="@style/Style_hLine" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/tv_two_bt_cancel"
            android:layout_width="@dimen/padding_0"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="取消"
            android:gravity="center"
            android:padding="@dimen/padding_10"
            style="@style/Font_Middle_Gray" />

        <View style="@style/Style_vLine" />

        <TextView
            android:id="@+id/tv_two_bt_ok"
            android:layout_width="@dimen/padding_0"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="确认"
            android:gravity="center"
            android:padding="@dimen/padding_10"
            style="@style/Font_Middle_Blue" />

    </LinearLayout>


</LinearLayout>

2,再贴显示pop的代码,之后使用直接new该类对象就可以了

package com.lzyc.ybtappcal.widget.popupwindow;

import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.PopupWindow;
import android.widget.TextView;

import com.lzyc.ybtappcal.R;
import com.lzyc.ybtappcal.util.DensityUtils;
import com.lzyc.ybtappcal.util.ScreenUtils;
import com.lzyc.ybtappcal.util.Util;

/**
 * 
 * 备注：towpopupwindow
 */
public class PopupWindowTwoButton extends PopupWindow {

    private Activity mContext;
    private TextView tv_title;
    private TextView tv_content;
    private TextView tv_cancel;
    private TextView tv_ok;

    public TextView getTv_title() {
        return tv_title;
    }

    public void setTv_title(TextView tv_title) {
        this.tv_title = tv_title;
    }

    public TextView getTv_content() {
        return tv_content;
    }

    public void setTv_content(TextView tv_content) {
        this.tv_content = tv_content;
    }

    public TextView getTv_cancel() {
        return tv_cancel;
    }

    public void setTv_cancel(TextView tv_cancel) {
        this.tv_cancel = tv_cancel;
    }

    public TextView getTv_ok() {
        return tv_ok;
    }

    public void setTv_ok(TextView tv_ok) {
        this.tv_ok = tv_ok;
    }

    public PopupWindowTwoButton(Activity context) {
        this.mContext = context;
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View conentView = inflater.inflate(R.layout.popup_two_button, null);

        tv_title = (TextView) conentView.findViewById(R.id.tv_two_bt_title);
        tv_content = (TextView) conentView.findViewById(R.id.tv_two_bt_content);
        tv_cancel = (TextView) conentView.findViewById(R.id.tv_two_bt_cancel);
        tv_ok = (TextView) conentView.findViewById(R.id.tv_two_bt_ok);


        int w = ScreenUtils.getScreenWidth() - DensityUtils.dp2px(60);
        int h = context.getWindowManager().getDefaultDisplay().getHeight();
        // 设置SelectPicPopupWindow的View
        this.setContentView(conentView);
        // 设置SelectPicPopupWindow弹出窗体的宽
        this.setWidth(w);
        // 设置SelectPicPopupWindow弹出窗体的高
        this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
        // 设置SelectPicPopupWindow弹出窗体可点击
        this.setFocusable(true);
        this.setOutsideTouchable(true);
        // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作
        this.setBackgroundDrawable(new BitmapDrawable());
        // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
        // 设置SelectPicPopupWindow弹出窗体动画效果
    }


    /**
     * 显示popupWindow
     *
     * @param parent
     */
    public void showPopupWindow(View parent, int gravity) {
        if (!this.isShowing()) {
            // 以下拉方式显示popupwindow
            Util.setBackgroundAlpha(mContext, 0.5f);
            this.showAtLocation(parent, gravity, 0, 0);
        } else {
            this.dismiss();
        }

    }

    @Override
    public void dismiss() {
        super.dismiss();
        Util.setBackgroundAlpha(mContext, 1f);
    }
}

//简单使用举例:

*申明一下,这里我的需求是取消和确定对调一下,使用这个的监听我写反了

    private void popupClearHistory() {
        final PopupWindowTwoButton twoButton = new PopupWindowTwoButton(this);
        twoButton.getTv_ok().setVisibility(View.VISIBLE);
        twoButton.getTv_title().setText("清空");
        twoButton.getTv_content().setText("你确定要清空历史记录吗?");
        twoButton.getTv_cancel().setText("确定");
        twoButton.getTv_cancel().setTextColor(Color.parseColor("#3E6398"));

        twoButton.getTv_ok().setText("取消");
        twoButton.getTv_ok().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                twoButton.dismiss();
                return;
            }
        });
        twoButton.getTv_cancel().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
             //确定的逻辑处理(本来是取消直接dismiss就可以了,但是我这里需求反了,所以在这里写确定的逻辑)
                twoButton.dismiss();
            }
        });
        twoButton.showPopupWindow(historyLinear, Gravity.CENTER);
    }

二:除了上面常见的使用之外,还有很多的地方使用到pop这里我就贴一个BasePopupwindow,之后使用到直接new该类的对象就可以了

package com.lzyc.ybtappcal.widget.popupwindow;

        return conentView;
    }

        this.conentView = conentView;
    }

    public BasePopupWindow(Activity context, int itemLayoutId, int w, int h) {
        this.mContext = context;
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        conentView = inflater.inflate(itemLayoutId, null);
//        int h = context.getWindowManager().getDefaultDisplay().getHeight();

        // 设置SelectPicPopupWindow的View
        this.setContentView(conentView);
        // 设置SelectPicPopupWindow弹出窗体的宽
        this.setWidth(w);
