Android仿IOS的PopupWindow和通用BasePopupWindow搭建

pw.png

1、BasePopupWindow.java

1.1、实现动态加载不同layout
1.2、动态配置是否弹出后背景半透明，关闭时候恢复（监听ondismiss，靠window类来变色）
1.3、一些基础性的方法抽象方法
1.4、为了更加复杂的样式和动效，可以继续扩展此类

/** * Created by wujn on 2018/10/29. * Version : v1.0 * Function: base popuwindow */ public abstract class BasePopupWindow extends PopupWindow implements View.OnClickListener{ /** * 上下文 */ private Context context; /** * 最上边的背景视图 */ private View vBgBasePicker; /** * 内容viewgroup */ private LinearLayout llBaseContentPicker; public BasePopupWindow(Context context) { super(context); this.cOntext= context; View parentView = View.inflate(context, R.layout.base_popup_window_picker, null); vBgBasePicker = parentView.findViewById(R.id.v_bg_base_picker); llBaseCOntentPicker= (LinearLayout) parentView.findViewById(R.id.ll_base_content_picker); /*** * 添加布局到界面中 */ llBaseContentPicker.addView(View.inflate(context, bindLayout(), null)); setContentView(parentView); //设置PopupWindow弹出窗体的宽 this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT); //设置PopupWindow弹出窗体的高 this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); //在PopupWindow里面就加上下面代码，让键盘弹出时，不会挡住pop窗口。 this.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED); this.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE); setFocusable(true);//设置获取焦点 setTouchable(true);//设置可以触摸 setOutsideTouchable(true);//设置外边可以点击 ColorDrawable dw = new ColorDrawable(0xffffff); setBackgroundDrawable(dw); //设置SelectPicPopupWindow弹出窗体动画效果 this.setAnimationStyle(R.style.BottomDialogWindowAnim); initView(parentView); initListener(); initData(); vBgBasePicker.setOnClickListener(this); //是否需要屏幕半透明 setBackgroundHalfTransition(isNeedBackgroundHalfTransition()); } /** * 初始化布局 * * @return */ protected abstract int bindLayout(); /** * 初始化view * * @param parentView */ protected abstract void initView(View parentView); /** * 初始化数据 */ protected abstract void initData(); /** * 初始化监听 */ protected abstract void initListener(); /** * 为了适配7.0系统以上显示问题(显示在控件的底部) * * @param anchor */ @Override public void showAsDropDown(View anchor) { if (Build.VERSION.SDK_INT >= 24) { Rect rect = new Rect(); anchor.getGlobalVisibleRect(rect); int h = anchor.getResources().getDisplayMetrics().heightPixels - rect.bottom; setHeight(h); } super.showAsDropDown(anchor); if(isNeedBgHalfTrans){ backgroundAlpha(0.5f); } } /** * 展示在屏幕的底部 * * @param layoutid rootview */ public void showAtLocation(@LayoutRes int layoutid) { showAtLocation(LayoutInflater.from(context).inflate(layoutid, null), Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0); if(isNeedBgHalfTrans){ backgroundAlpha(0.5f); } } /** * 最上边视图的点击事件的监听 * * @param v */ @Override public void onClick(View v) { switch (v.getId()) { case R.id.v_bg_base_picker: dismiss(); break; } } /** * 是否设置背景半透明 * */ public boolean isNeedBackgroundHalfTransition(){ return false; } private boolean isNeedBgHalfTrans = false; private void setBackgroundHalfTransition(boolean isNeed){ isNeedBgHalfTrans = isNeed; if(isNeedBgHalfTrans){ this.setOnDismissListener(new OnDismissListener() { @Override public void onDismiss() { backgroundAlpha(1f); } }); } } /** * 设置添加屏幕的背景透明度 * @param bgAlpha */ private void backgroundAlpha(float bgAlpha) { WindowManager.LayoutParams lp = ((Activity)context).getWindow().getAttributes(); lp.alpha = bgAlpha; //0.0-1.0 ((Activity)context).getWindow().setAttributes(lp); } } 

2、base_popup_window_picker.xml

3、进入和退出时候的动画style

进入动画：popup_bottom_enter_anim.xml

退出动画：popup_bottom_exit_anim.xml

4、仿IOS的layout：popup_window_album_or_camera.xml

item的背景style

5、仿IOS的popuwindow类：AlbumOrCameraPopupWindow

public class AlbumOrCameraPopupWindow extends BasePopupWindow { private Button btnCamera; private Button btnAlbum; private Button btnCancel; private OnCameraOrAlbumSelectListener onCameraOrAlbumSelectListener; public AlbumOrCameraPopupWindow(Context context,OnCameraOrAlbumSelectListener onCameraOrAlbumSelectListener) { super(context); this.OnCameraOrAlbumSelectListener= onCameraOrAlbumSelectListener; } @Override public boolean isNeedBackgroundHalfTransition(){ return true; } @Override protected int bindLayout() { return R.layout.popup_window_album_or_camera; } @Override protected void initView(View parentView) { btnCamera = (Button) parentView.findViewById(R.id.btnCamera); btnAlbum = (Button) parentView.findViewById(R.id.btnAlbum); btnCancel = (Button) parentView.findViewById(R.id.btnCancel); } @Override protected void initData() { } @Override protected void initListener() { btnCamera.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dismiss(); if(onCameraOrAlbumSelectListener != null){ onCameraOrAlbumSelectListener.OnSelectCamera(); } } }); btnAlbum.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dismiss(); if(onCameraOrAlbumSelectListener != null){ onCameraOrAlbumSelectListener.OnSelectAlbum(); } } }); btnCancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dismiss(); } }); } } 

选择相机或者相册的监听接口

public interface OnCameraOrAlbumSelectListener { public void OnSelectCamera(); public void OnSelectAlbum(); } 

6、具体使用

private AlbumOrCameraPopupWindow ACWindow; private void initListener(){ ACWindow = new AlbumOrCameraPopupWindow(this, onCameraOrAlbumSelectListener); btnIosPopupWindow.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(ACWindow != null && !ACWindow.isShowing()){ ACWindow.showAtLocation(R.layout.activity_view_popup_window); } } }); } /**选择相机或者相册*/ private OnCameraOrAlbumSelectListener OnCameraOrAlbumSelectListener= new OnCameraOrAlbumSelectListener() { @Override public void OnSelectCamera() { LogUtil.i("OnSelectCamera..."); ToastUtil.showShort(instance, "相机"); } @Override public void OnSelectAlbum() { LogUtil.i("OnSelectAlbum..."); ToastUtil.showShort(instance, "从相册中选择"); } };
