1.圆形图片
a.在项目里加入以下代码

mBitmapShader.setLocalMatrix(mShaderMatrix);
}
}
b.在XML文件里这样使用
<view.CircleImageView
android:id="@+id/call"
android:layout_width="160dp"
android:layout_height="160dp"
android:layout_centerInParent="true"
android:src="@mipmap/shuang"
app:border_width="2dp"
app:border_color="@color/colorAccent" />
2.PopWindow 弹出窗口
a.在项目里加入以下代码
package com.example.helloworld;
import android.content.Context;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
/**
* Created by 任亚捷 on 2016/5/20.
*/
public class MyListener implements View.OnClickListener{
private Context context;
private int index;
private String[] sentence = {"bao","gao","zhong","shui","qing","jia","yang"};
private Button button;
MyListener(Context context, int index, Button button)
{
this.context = context;
this.index = index;
this.button = button;
}
/**
* Called when a view has been clicked.
*
* @param v The view that was clicked.
*/
@Override
public void onClick(View v) {
Toast.makeText(context,sentence[index],Toast.LENGTH_SHORT).show();
}
}

package com.example.helloworld;
import android.content.Context;

import android.view.Gravity;

import android.view.View;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.PopupWindow;
/**
* Created by 任亚捷 on 2016/5/20.
*/
public class MyPop {
private Context context;
private Button button;
private int[] resID = {R.id.baomu, R.id.gaoji, R.id.zhongdian, R.id.shuidian, R.id.qingjie,
R.id.jiajiao, R.id.yanghu};
private Button[] buttons;
private MyListener[] listeners;
MyPop(Context context, Button button) {
this.context = context;
this.button = button;
listeners = new MyListener[7];
buttons = new Button[7];
}
protected void initView() {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.popwindow, null);
// 下面是两种方法得到宽度和高度 getWindow().getDecorView().getWidth()
PopupWindow window = new PopupWindow(view,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.WRAP_CONTENT);
// 设置popWindow弹出窗体可点击，这句话必须添加，并且是true
window.setFocusable(true);
// 实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0xb0000000);
window.setBackgroundDrawable(dw);
// 设置popWindow的显示和消失动画
window.setAnimationStyle(R.style.mypopwindow_anim_style);
// 在底部显示
window.showAtLocation(button, Gravity.BOTTOM, 0, 0);
//popWindow消失监听方法
window.setOnDismissListener(new PopupWindow.OnDismissListener() {
@Override
public void onDismiss() {
System.out.println("popWindow消失");
}
});
for (int i = 0; i < resID.length; i++) {
buttons[i] = (Button) view.findViewById(resID[i]);
listeners[i] = new MyListener(context, i, buttons[i]);
buttons[i].setOnClickListener(listeners[i]);
}
}
}
其中我在弹出窗口中用了7个按钮，在实际项目中可根据需求自己修改即可，在MainActivity中初始化MyPop然后调用initview()方法即可.
