在Android中,要实现Loading效果，一般情况下都使用ProgressDialog控件。ApiDemos/src/com/example/android/apis/view/ProgressBar3.java 提供两个demo:

仔细看了Android Market，发现却是不一样的，请看截图: 那到底如何实现呢？首先，我们创建一个布局文件, res/layout/fullscreen_loading_indicator.xml, 其内容如下:

 <?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:gravity="center_vertical|center_horizontal"    android:orientation="horizontal"    android:id="@+id/fullscreen_loading_indicator"    android:visibility="gone"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    >    <ProgressBar        android:layout_gravity="center_vertical"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        style="?android:attr/progressBarStyleSmall"        >    </ProgressBar>    <TextView        android:id="@+id/current_action"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginLeft="5.0dip"        android:text="@string/loading"        >    </TextView></LinearLayout>

然后在main.xml 把它include 进来

 <?xml version="1.0" encoding="utf-8"?><FrameLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    >    <LinearLayout        android:orientation="vertical"        android:id="@+id/main_info"        android:visibility="gone"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        >    </LinearLayout>    <include        android:visibility="visible"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        layout="@layout/fullscreen_loading_indicator"        >    </include></FrameLayout>

主程序 Loading.java:

package org.lytsing.android.loading;import android.app.Activity;import android.os.Bundle;import android.widget.LinearLayout;public class Loading extends Activity {    private LinearLayout mLoadingLayout;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        // TODO: dismiss the loading, use this snippet code.        //mLoadingLayout = (LinearLayout)findViewById(R.id.fullscreen_loading_indicator);        //mLoadingLayout.setVisibility(View.GONE);    }}
