Android仿ios底部弹出框效果

准备：

public class ActionSheet {
   public interface OnActionSheetSelected {
      void onClick(int whichButton);
   }

   private ActionSheet() {
   }

   public static Dialog showSheet(final Context context, final int layoutId,
         final OnActionSheetSelected actionSheetSelected,
         final OnCancelListener cancelListener) {
      final Dialog dialog = new Dialog(context, R.style.ActionSheet);
      final LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      final LinearLayout layout = (LinearLayout) inflater.inflate(layoutId,
            null);
      final int cFullFillWidth = 10000;
      layout.setMinimumWidth(cFullFillWidth);

      final Window w = dialog.getWindow();
      final WindowManager.LayoutParams lp = w.getAttributes();
      lp.x = 0;
      final int cMakeBottom = -1000;
      lp.y = cMakeBottom;
      lp.gravity = Gravity.BOTTOM;
      dialog.onWindowAttributesChanged(lp);
      dialog.setCanceledOnTouchOutside(true);
      if (cancelListener != null) {
         dialog.setOnCancelListener(cancelListener);
      }

      dialog.setContentView(layout);
      dialog.show();

      return dialog;
   }
}

<style name="ActionSheet" parent="@android:style/Theme.Dialog">

应用：

private ActionSheet.OnActionSheetSelected mOnActionSheetSelected;

private Dialog mActionSheet;

调用showGetPhotoDialog()方法：

public void onActionSheetClicked(final View view) {
   mOnActionSheetSelected.onClick(view.getId());
}

public void setOnSheetClicked(final ActionSheet.OnActionSheetSelected onActionSheetSelected) {
   mOnActionSheetSelected = onActionSheetSelected;
}

private void showGetPhotoDialog() {
   mActionSheet = ActionSheet.showSheet(this, R.layout.actionsheet_dialog, getOnActionSheetClicked(), null);
}

private ActionSheet.OnActionSheetSelected getOnActionSheetClicked() {

   return new ActionSheet.OnActionSheetSelected() {

      @Override
      public void onClick(final int whichButton) {
         switch (whichButton) {
            case R.id.tv_button1:

               break;

 	    case R.id.tv_button2:

               break;

　　　　　　case R.id.tv_calendar: 
　　　　　　　　 mActionSheet.dismiss();
               break;
          default: 
              break; 
          }
           mActionSheet.dismiss(); }
 　　　　　};
}
