android popwindow仿微信右上方彈出框，dialog底部顯示

android popwindow仿右上方彈出框，dialog底部顯示
仿右上方彈出框1、利用popwindow實現2、popwindow的位置居於右上方建立，彈出popwindow：

/** 彈popwindow **/tv = (TextView) findViewById(R.id.textView1);view_pop = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_menu, null);tv.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {if (mPopupwinow == null) {//建立一個popwindowmPopupwinow = new PopupWindow(view_pop,LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, true);//設定popwindow的背景顏色mPopupwinow.setBackgroundDrawable(new ColorDrawable(0x00000000));}//設定popwindow的位置  tv:為右上方+號view，居於+號下方mPopupwinow.showAsDropDown(tv, 0, 0);}});

布局pop_menu.xml：

效果：


1、螢幕下方dialog建立dialog，設定dialog的位置

/** 彈dialog **/private void showDialog() {dialog = new Dialog(this,R.style.dialog);view_dialog = LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog_layout, null);dialog.setContentView(view_dialog);TextView tv_cancle = (TextView) view_dialog.findViewById(R.id.tv_cancle);tv_cancle.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {dialog.dismiss();}});/* * 擷取聖誕框的視窗對象及參數對象以修改對話方塊的布局設定, 可以直接調用getWindow(),表示獲得這個Activity的Window * 對象,這樣這可以以同樣的方式改變這個Activity的屬性. */Window dialogWindow = dialog.getWindow();//設定位置dialogWindow.setGravity(Gravity.BOTTOM);//設定dialog的寬高屬性dialogWindow.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);dialog.show();}

xml：

R.style.dialog：
