1.定義進度對話方塊類

<span style="font-size:18px;">public class ProgressDialog {
	public Dialog mDialog;
	private AnimationDrawable animationDrawable = null;

	public ProgressDialog(Context context, String message) {

		LayoutInflater inflater = LayoutInflater.from(context);
		View view = inflater.inflate(R.layout.progress_view, null);

		TextView text = (TextView) view.findViewById(R.id.progress_message);
		text.setText(message);
		ImageView loadingImage = (ImageView) view.findViewById(R.id.progress_view);
		loadingImage.setImageResource(R.drawable.progress_dialog_loding);
		animationDrawable = (AnimationDrawable)loadingImage.getDrawable();
		if(animationDrawable!=null){
			animationDrawable.setOneShot(false);
			animationDrawable.start();
		}

		mDialog = new Dialog(context, R.style.dialog);
		mDialog.setContentView(view);
		mDialog.setCanceledOnTouchOutside(false);

	}

	public void show() {
		mDialog.show();
	}

	public void setCanceledOnTouchOutside(boolean cancel) {
		mDialog.setCanceledOnTouchOutside(cancel);
	}

	public void dismiss() {
		if(mDialog.isShowing()) {
			mDialog.dismiss();
			animationDrawable.stop();
		}
	}
	public boolean isShowing(){
		if(mDialog.isShowing()) {
			return true;
		}
		return false;
	}
}</span>
 

2. 對話方塊佈局檔案

<span style="font-size:18px;"><?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:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_gravity="center"
        android:background="@drawable/progress_bg"
        android:gravity="center"
        android:orientation="vertical">

        <ImageView
            android:id="@+id/progress_view"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:src="@mipmap/bga_refresh_loading01"/>

        <TextView
            android:id="@+id/progress_message"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#d1d4d7"
            android:textSize="13sp"/>
    </LinearLayout>

</FrameLayout></span>
 

<span style="font-size:18px;">progress_dialog_loding.xml 圖片載入動畫</span>

<pre name="code" class="html"><span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false" >

    <item
        android:drawable="@mipmap/bga_refresh_loading01"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading02"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading03"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading04"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading05"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading06"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading07"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading08"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading09"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading10"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading11"
        android:duration="100"/>
    <item
        android:drawable="@mipmap/bga_refresh_loading12"
        android:duration="100"/>

</animation-list></span>
 

4.用到的圖片資源

5.在activity中使用

在onResume方法中

<span style="font-size:18px;">if (progressDialog == null) {
			progressDialog = new ProgressDialog(mContext, "正在載入...");
			progressDialog.show();
		}</span>

progressDialog.dismiss();方法
