自定义Dialog

首先创建style.xml

<!-- Dialog的Style -->
    <style name="loading_dialog" parent="android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item> 
        <item name="android:windowBackground">@drawable/loading_bg</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

然后自定义布局文件：common_dialog_progress.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="match_parent"
    android:minHeight="40dp"
    android:minWidth="130dp"
    android:gravity="center"
    android:orientation="vertical">
 
    <ProgressBar
        android:layout_marginTop="28dp" 
        android:id="@+id/dialog_progress"
        android:layout_height="41dp"
        android:layout_width="41dp"
        android:indeterminateDrawable="@drawable/image_progress_upload"/>
 
    <TextView
        android:textColor="@android:color/white" 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_marginTop="20dp"
        android:layout_marginBottom="20dp"
        android:text="@string/label_upload_text"/>       
</LinearLayout>

最后调用：

/**     * 弹出一个带有进度条的弹出框     * @param context     * @return Dialog     */
    public static Dialog progressDialog(Context context) {
        Dialog dialog = new Dialog(context, R.style.loading_dialog);
        dialog.setCancelable(false);
        dialog.show();
        View v = LayoutInflater.from(context).inflate(R.layout.common_dialog_progress, null);
        dialog.setContentView(v,new LinearLayout.LayoutParams(  
                LinearLayout.LayoutParams.FILL_PARENT,  
                LinearLayout.LayoutParams.FILL_PARENT));
 
        return dialog;
    }
 
    /**     * 关闭带进度条的弹出框     * @param dialog     */
    public  static  void closeDialog(Dialog dialog) {
        if (dialog !=null) {
            dialog.dismiss();
        }
    }
