Android 自定义DialogProgress

/**
 * @Description:自定义对话框
 */
public class MProgressDialog extends ProgressDialog {

	private AnimationDrawable mAnimation;
	private Context mContext;
	private ImageView mImageView;
	private String mLoadingTip;
	private TextView mLoadingTv;
	private int count = 0;
	private String oldLoadingTip;
	private int mResid;

	/**
	 * 
	 * @param context
	 *            上下文对象
	 * @param content
	 *            显示文字提示信息内容
	 * @param id
	 *            动画id
	 */
	public <span style="font-family: Arial, Helvetica, sans-serif;">MProgressDialog</span>(Context context, String content, int id) {
		super(context);
		this.mContext = context;
		this.mLoadingTip = content;
		this.mResid = id;
		setCanceledOnTouchOutside(true);
	}

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		initView();
		initData();
	}

	private void initData() {

		mImageView.setBackgroundResource(mResid);
		// 通过ImageView对象拿到背景显示的AnimationDrawable
		mAnimation = (AnimationDrawable) mImageView.getBackground();

		mImageView.post(new Runnable() {
			@Override
			public void run() {
				mAnimation.start();

			}
		});
		mLoadingTv.setText(mLoadingTip);

	}

	public void setContent(String str) {
		mLoadingTv.setText(str);
	}

	private void initView() {
		setContentView(R.layout.progress_dialog);// 显示界面
		mLoadingTv = (TextView) findViewById(R.id.loadingTv);
		mImageView = (ImageView) findViewById(R.id.loadingIv);
	}

}

调用Activity代码：

public class ManActivity extends Activity {
	private MProgressDialog dialog;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout._progressdialog);
	}
	/**
	 * 显示美团进度对话框
	 * @param v
	 */
	public void showmeidialog(View v){
		dialog =new MProgressDialog(this, "正在加载中",R.anim.frame_animation);
		dialog.show();
		Handler handler =new Handler();
		handler.postDelayed(new Runnable() {
			
			@Override
			public void run() {
				
				dialog.dismiss();
			}
		}, 3000);//3秒钟后调用dismiss方法隐藏；
		
	}
	
}

R.anim.frame_animation 代码：就是两张动画图片

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false" >

    <item
        android:drawable="@drawable/progress_loading_image_01"
        android:duration="150"/>
    <item
        android:drawable="@drawable/progress_loading_image_02"
        android:duration="150"/>

</animation-list>

R.layout._progressdialog代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
   android:layout_gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/loadingIv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@anim/frame_animation"/>

    <TextView
        android:id="@+id/loadingTv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
		android:layout_alignBottom="@+id/loadingIv"
		
		android:layout_centerHorizontal="true"
		android:textSize="20sp"
        android:text="正在加载中.." />

</RelativeLayout>

就这样OK了。
