仿iOS的网络请求的加载框

/**

* 发送请求后的加载框

*

* @param myView

* @param msg

*/

public void showPopupWindow(View myView, String msg) {

PopupWindow popupWindow ;

View contentView = LayoutInflater.from(mContext).inflate(R.layout.loading_progress_dialog, null);

TextView load_msg = (TextView) contentView.findViewById(R.id.tv_loading_message);

load_msg.setText(msg);

contentView.setFocusable(true);

contentView.setFocusableInTouchMode(true);

popupWindow = new PopupWindow(contentView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

popupWindow.setFocusable(true);

popupWindow.setOutsideTouchable(false);

contentView.setOnKeyListener(new View.OnKeyListener() {

@Override

public boolean onKey(View v, int keyCode, KeyEvent event) {

popupWindow.dismiss();

return false;

}

});

popupWindow.showAtLocation(myView, Gravity.CENTER | Gravity.CENTER_HORIZONTAL, 0, 0);

}

myView这个参数表示的是弹窗所在的这个界面的布局，即整体布局

弹窗的布局：

<?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="match_parent"

android:background="@drawable/tips_bg"

android:gravity="center"

android:orientation="vertical"

android:padding="10dp" >

<ProgressBar

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:indeterminateDrawable="@drawable/frame_loading" />

<TextView

android:id="@+id/tv_loading_message"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

android:textColor="@color/white"

android:textSize="15sp" />

</LinearLayout>

frame_loading中的写法

<?xml version="1.0" encoding="UTF-8"?>

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"

android:oneshot="false" >

<item android:duration="150">

<clip

android:clipOrientation="horizontal"

android:drawable="@drawable/loading_01"

刚写微博，不会多张上传，所以只附上一张示例图片，其他的可以去网上找一找.

代码都上传上来了，有兴趣的可以试一试，如果不满意popupWindow 的每次都要写myview，可以换成dialog，效果也是可以的。
