在做微信、微博、qq等分享时,一般是点击分享按钮后会从底部弹出滑动窗口,然后选择要分享的社交平台进行分享。今日头条、腾讯新闻等内容App的评论也是从底部滑动弹出输入窗口,进行评论输入的。本篇文章就讲讲怎么通过Activity实现底部弹出滑动窗口的。实现效果是通过Animation功能实现的,效果如下: 源码下载地址
主要代码如下:
一、滑动窗口PopupShareActivity类
继承自Activity并实现了OnClickListener,方便处理Click事件。代码如下:
public class PopupShareActivity extends Activity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_popup_share);
//全屏Activity操作
getWindow().setLayout(WindowManager.LayoutParams.FILL_PARENT, WindowManager.LayoutParams.FILL_PARENT);
//QQ分享按钮
ImageBtn MyIBtn1 = (ImageBtn)findViewById(R.id.MyIBtn_1);
MyIBtn1.setImageResource(R.drawable.ic_share_qq);
MyIBtn1.setText("QQ");
ImageBtn MyIBtn2 = (ImageBtn)findViewById(R.id.MyIBtn_2);
MyIBtn2.setImageResource(R.drawable.ic_share_sina);
MyIBtn2.setText("微博");
ImageBtn MyIBtn3 = (ImageBtn)findViewById(R.id.MyIBtn_3);
MyIBtn3.setImageResource(R.drawable.ic_share_wechat);
MyIBtn3.setText("微信");
ImageBtn MyIBtn4 = (ImageBtn)findViewById(R.id.MyIBtn_4);
MyIBtn4.setImageResource(R.drawable.ic_share_wxcircle);
MyIBtn4.setText("朋友圈");
Button btn_cancel = (Button) this.findViewById(R.id.btn_cancel);
btn_cancel.setOnClickListener(this);
}
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btn_cancel:
break;
default:
break;
}
finish();
}
}
二、分享类布局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto";
android:gravity="center_horizontal"
android:orientation="vertical">
<LinearLayout
android:id="@+id/pop_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:background="@color/color_white"
>
<LinearLayout
android:id="@+id/share_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:background="@color/color_white"
>
<com.jxkj.bbccode.anxiuyunslid.component.ImageBtn
android:id="@+id/MyIBtn_1"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="1.0"
android:clickable="true"
android:focusable="true"
/>
<com.jxkj.bbccode.anxiuyunslid.component.ImageBtn
android:id="@+id/MyIBtn_2"
android:layout_width="0dp"
android:layout_weight="1.0"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
/>
<com.jxkj.bbccode.anxiuyunslid.component.ImageBtn
android:id="@+id/MyIBtn_3"
android:layout_width="0dp"
android:layout_weight="1.0"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
/>
<com.jxkj.bbccode.anxiuyunslid.component.ImageBtn
android:id="@+id/MyIBtn_4"
android:layout_width="0dp"
android:layout_weight="1.0"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
/>
</LinearLayout>
<Button
android:id="@+id/btn_cancel"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="15dip"
android:layout_marginBottom="15dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="取消"
android:textColor="#ffffff"
android:textStyle="bold"
/>
</LinearLayout>
</RelativeLayout>
三、AndroidManifest添加Activity配置
<activity android:name=".activity.PopupShareActivity"
android:theme="@style/PopupShareActivity">
四、PopupShareActivity主题
<style name="MyDialogStyleBottom" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowAnimationStyle">@style/AnimBottom</item>
<item name="android:windowFrame">@null</item>
<!-- 边框 -->
<item name="android:windowIsFloating">true</item>
<!-- 是否浮现在activity之上 -->
<item name="android:windowIsTranslucent">true</item>
<!-- 半透明 -->
<item name="android:windowNoTitle">true</item>
<!-- 无标题 -->
<item name="android:windowBackground">@android:color/transparent</item>
<!-- 背景透明 -->
<item name="android:backgroundDimEnabled">true</item>
<!-- 模糊 -->
</style>
<style name="AnimBottom" parent="@android:style/Animation">
<item name="android:windowEnterAnimation">@anim/push_bottom_in</item>
<item name="android:windowExitAnimation">@anim/push_bottom_out</item>
</style>
五、Animation动画效果
在anim目下下定义xml文件分别为:
<!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android"; >
<translate
android:duration="200"
android:fromYDelta="100%p"
android:toYDelta="0"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑出式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android"; >
<translate
android:duration="200"
android:fromYDelta="0"
android:toYDelta="50%p" />
</set>
