仿微信右上角弹出框
1、利用popwindow实现
2、popwindow的位置居于右上角
新建，弹出popwindow：
/** 弹popwindow **/
<span style="white-space:pre"> </span>tv = (TextView) findViewById(R.id.textView1);
<span style="white-space:pre"> </span>view_pop = LayoutInflater.from(MainActivity.this).inflate(
<span style="white-space:pre"> </span>R.layout.pop_menu, null);
<span style="white-space:pre"> </span>tv.setOnClickListener(new OnClickListener() {
<span style="white-space:pre"> </span>@Override
<span style="white-space:pre"> </span>public void onClick(View arg0) {
<span style="white-space:pre"> </span>if (mPopupwinow == null) {
<span style="white-space:pre"> </span>//新建一个popwindow
<span style="white-space:pre"> </span>mPopupwinow = new PopupWindow(view_pop,
<span style="white-space:pre"> </span>LayoutParams.WRAP_CONTENT,
<span style="white-space:pre"> </span>LayoutParams.WRAP_CONTENT, true);
<span style="white-space:pre"> </span>//设置popwindow的背景颜色
<span style="white-space:pre"> </span>mPopupwinow.setBackgroundDrawable(new ColorDrawable(
<span style="white-space:pre"> </span>0x00000000));
<span style="white-space:pre"> </span>}
<span style="white-space:pre"> </span>//设置popwindow的位置 tv:为微信右上角+号view，居于+号下方
<span style="white-space:pre"> </span>mPopupwinow.showAsDropDown(tv, 0, 0);
<span style="white-space:pre"> </span>}
<span style="white-space:pre"> </span>});

效果：
1、屏幕下方dialog
创建dialog，设置dialog的位置
/** 弹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() {
@Override
public void onClick(View arg0) {
dialog.dismiss();
}
});
/*
* 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getWindow(),表示获得这个Activity的Window
* 对象,这样这可以以同样的方式改变这个Activity的属性.
*/
Window dialogWindow = dialog.getWindow();
//设置位置
dialogWindow.setGravity(Gravity.BOTTOM);
//设置dialog的宽高属性
dialogWindow.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
dialog.show();
}
xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="150dp"
android:gravity="bottom|center_horizontal"
android:orientation="vertical" >
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#efefef" />
<TextView
android:id="@+id/tv_cancle"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:text="取消"
android:textSize="20sp" />
</LinearLayout>
</LinearLayout>
R.style.dialog：
<!--dialog样式-->
<style name="dialog" parent="@android:style/Theme.Dialog">
<item name="android:windowIsFloating">true</item>
<!-- 设置未浮动窗口 -->
<item name="android:windowFrame">@null</item>
<!-- 设置无边框 -->
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<!-- 设置无标题 -->
<item name="android:windowBackground">@color/sc_transparent_background</item>
<!-- 设置完全透明 -->
