Android_下方弹出菜单的实现 _Android_

识字粗堪供赋役，不须辛苦慕公卿。这篇文章主要讲述Android_下方弹出菜单的实现相关的知识，希望能为你提供帮助。
这一功能要用到动画相关知识
【Android_下方弹出菜单的实现】实现点击按钮弹出下方输入框,这里点击可弹出一个输入界面，其中包括一个小型计算器。
点击date可弹出datedialog设置date。

1、编写弹出框的布局文件

3、在Activity中实现2中的接口

public void send(int n) { Dialog mCameraDialog = new Dialog(this, R.style.BottomDialog); RelativeLayout root = (RelativeLayout) LayoutInflater.from(this).inflate( R.layout.layout_fragment_calcul, null); CalculFragment calculFragment=new CalculFragment(root,MainActivity.this); root=calculFragment.bindandset(root); mCameraDialog.setContentView(root); Window dialogWindow = mCameraDialog.getWindow(); dialogWindow.setGravity(Gravity.BOTTOM); dialogWindow.setWindowAnimations(R.style.DialogAnimation); // 添加动画 WindowManager.LayoutParams lp = dialogWindow.getAttributes(); // 获取对话框当前的参数值 lp.x = 0; // 新位置X坐标 lp.y = 0; // 新位置Y坐标 lp.width = (int) getResources().getDisplayMetrics().widthPixels; // 宽度 root.measure(0, 0); lp.height = root.getMeasuredHeight(); //lp.alpha = 9f; // 透明度 dialogWindow.setAttributes(lp); mCameraDialog.show(); }

style

< style name="BottomDialog" parent="@android:style/Theme.Dialog"> < !-- 背景透明 --> < item name="android:windowBackground"> @android:color/transparent< /item> < item name="android:windowContentOverlay"> @null< /item> < !-- 浮于Activity之上 --> < item name="android:windowIsFloating"> true< /item> < !-- 边框 --> < item name="android:windowFrame"> @null< /item> < !-- Dialog以外的区域模糊效果 --> < item name="android:backgroundDimEnabled"> true< /item> < !-- 无标题 --> < item name="android:windowNoTitle"> true< /item> < !-- 半透明 --> < item name="android:windowIsTranslucent"> true< /item> < !-- Dialog进入及退出动画 --> < item name="android:windowAnimationStyle"> @style/DialogAnimation< /item> < /style> < !-- ActionSheet进出动画 --> < style name="DialogAnimation" parent="@android:style/Animation.Dialog"> < item name="android:windowEnterAnimation"> @anim/dialog_in< /item> < item name="android:windowExitAnimation"> @anim/dialog_out< /item> < /style>
