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
