实现
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

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");
}
};
朝CV工程师又进一步~~~
2018/11/05 更新： BasePopupWindow.java 优化：
- 1、先initData在initListener ，比较好一点
- 2、protected context，子类有可能也需要用到，有时候需要加recyleview
