东西很简单，我就直接亮代码了：
1、activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
2、MainActivity.java
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private SelectPicPopupWindow menuWindow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.bt_select_image).setOnClickListener(this);
}
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.bt_select_image:
//TODO implement
selectImgs();
}
}
private void selectImgs(){
menuWindow = new SelectPicPopupWindow(MainActivity.this, itemsOnClick);
//设置弹窗位置
menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.ll_image), Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
}
private View.OnClickListener itemsOnClick = new View.OnClickListener() {
public void onClick(View v) {
menuWindow.dismiss();
switch (v.getId()) {
case R.id.item_popupwindows_camera: //点击拍照按钮
break;
case R.id.item_popupwindows_Photo: //点击从相册中选择按钮
break;
default:
break;
}
}
};
}
3、关键代码：SelectPicPopupWindow.java
**public class SelectPicPopupWindow extends PopupWindow {
private Button item_popupwindows_camera, //弹窗拍照按钮
item_popupwindows_Photo, //弹窗从相册选择按钮
item_popupwindows_cancel; //弹窗取消按钮
private View menuview;
/**
* 上传图片*************************
* @param context
* @param itemsOnclick
*/
public SelectPicPopupWindow(Activity context, View.OnClickListener itemsOnclick){
super(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
menuview = inflater.inflate(R.layout.item_popupwindows,null);
item_popupwindows_camera = (Button) menuview.findViewById(R.id.item_popupwindows_camera); //拍照按钮
item_popupwindows_cancel = (Button) menuview.findViewById(R.id.item_popupwindows_cancel); //取消按钮
item_**popupwindows_Photo = (Button) menuview.findViewById(R.id.item_popupwindows_Photo); //图库按钮
/**
* 取消按钮销毁事件
*/
item_popupwindows_cancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
dismiss();
}
});
item_popupwindows_camera.setOnClickListener(itemsOnclick);
item_popupwindows_Photo.setOnClickListener(itemsOnclick);
//设置SelectPicPopupWindow的View
this.setContentView(menuview);
//设置SelectPicPopupWindow**弹出窗体的宽
this.setWidth(ViewGroup.LayoutParams.FILL_PARENT);
//设置SelectPicPopupWindow弹出窗体的高
//修改高度显示，解决被手机底部虚拟键挡住的问题 by黄海杰 at:2015-4-30
this.setHeight(ViewGroup.LayoutParams.MATCH_PARENT);
//设置SelectPicPopupWindow弹出窗体可点击
this.setFocusable(true);
//设置SelectPicPopupWindow弹出窗体动画效果
//this.setAnimationStyle(R.style);
//实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0xb0000000);
//设置SelectPicPopupWindow弹出窗体的背景
this.setBackgroundDrawable(dw);
//menuview添加ontouchlistener监听判断获取触屏位置如果在选择框外面则销毁弹出框
menuview.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View view, MotionEvent motionEvent) {
int height = menuview.findViewById(R.id.ll_popup).getTop();
int y = (int) motionEvent.getY();
if (motionEvent.getAction() == MotionEvent.ACTION_UP){
if (y写的不好，请见谅，，下一期完成后期的工作！
