之前传了github，忘了更新，给大家带来的不便请谅解！

京东筛选更新了，很好，很炫酷。那什么，我们也不差是吧，于是就有了这个demo。话不多说，先看图，不想看代码的朋友，直接点底部下demo。
图1里面呢，就两点，弹出的PopupWindow的高度为屏幕高的一半，另一半为半透明高端黑，简单点就用weight属性来写，方便快捷。然后在上半部分写个GridView，在GridView的底部有个LinearLayout，用来放俩Button，但是Button比较难处理布局，本着高仿的原则，我还是用的TextView。哈哈，机智如我。
先来看看这个PopupWindow的布局吧：
<?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="match_parent" android:background="#33000000" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:background="#ffffff" android:orientation="vertical"> <GridView android:id="@+id/grid" android:layout_width="match_parent" android:layout_height="0dp" android:layout_marginTop="14dp" android:layout_weight="1" android:horizontalSpacing="14dp" android:numColumns="3" android:verticalSpacing="14dp" /> <LinearLayout android:layout_width="match_parent" android:layout_height="48dp" android:orientation="vertical"> <View android:layout_width="match_parent" android:layout_height="1px" android:background="#cccccc" /> <LinearLayout android:layout_width="match_parent" android:layout_height="48dp"> <TextView android:id="@+id/reset" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:gravity="center" android:text="重置" /> <TextView android:id="@+id/ok" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="#ff0033" android:gravity="center" android:text="确定" android:textColor="#ffffff" /> LinearLayout> LinearLayout> LinearLayout> <View android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" />LinearLayout>布局简单吧，反正我是没怎么费脑筋就给搞出来的。下面来看看PopupWindow的代码：
package lx.com.filter.view;import android.app.Activity;import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.view.LayoutInflater;import android.view.View;import android.widget.AdapterView;import android.widget.GridView;import android.widget.PopupWindow;import android.widget.TextView;import android.widget.Toast;import java.util.List;import lx.com.filter.R;import lx.com.filter.adapter.PopupAdapter;import lx.com.filter.vo.Vo;public class PricePopup extends PopupWindow { private View contentView; private GridView grid; private TextView reset; private TextView ok; private PopupAdapter adapter; private List data; public PricePopup(final Activity context, final List data) { this.data = data; adapter = new PopupAdapter(context); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); contentView = inflater.inflate(R.layout.popup, null); grid = (GridView) contentView.findViewById(R.id.grid); reset = (TextView) contentView.findViewById(R.id.reset); ok = (TextView) contentView.findViewById(R.id.ok); grid.setAdapter(adapter); grid.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) { data.get(position).setChecked(!data.get(position).isChecked()); for (int i = 0; i < data.size(); i++) { if (i == position) { continue; } data.get(i).setChecked(false); } Toast.makeText(context, data.get(position).getStr2(), Toast.LENGTH_SHORT).show(); adapter.notifyDataSetChanged(data); } }); int h = context.getWindowManager().getDefaultDisplay().getHeight(); int w = context.getWindowManager().getDefaultDisplay().getWidth(); this.setContentView(contentView); this.setWidth(w); this.setHeight(h); ColorDrawable dw = new ColorDrawable(00000000); this.setBackgroundDrawable(dw); this.setFocusable(true); this.setOutsideTouchable(false); this.update(); } public void showPricePopup(View parent, final List data) { if (!this.isShowing()) { this.showAsDropDown(parent); adapter.notifyDataSetChanged(data); } else { this.dismiss(); } }} Adapter就不放了，demo里面有的。接下来，图2里面的就比较复杂了。还是先看布局吧：

这个是单选的：

突然还想起个问题，之前用Android Studio没有配好Gradle，于是就用的Eclipse先写的，导出的时候选的Gradle，再用Android Studio编辑的，结果报错了，大概意思就是Gradle版本的问题，于是乎：
gradle编译时失败报错，需将 项目名称\gradle\wrapper\gradle-wrapper.properties里的distributionUrl=http\://services.gradle.org/distributions/gradle-1.12-all.zip改为distributionUrl=http\://services.gradle.org/distributions/gradle-2.10-all.zip后面的数字即开发环境配置中gradle的版本更多相关文章
