Android之仿美团加载数据帧动画

-----------------转载请注明出处：http://blog.csdn.net/android_cll

一：先来张效果图(这里是GIF动画，我就截屏的所有没有动画，实际是动的)：

二：实现步骤：

1、xml布局、

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


            android:id="@+id/textview"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_alignParentBottom="true"
        android:layout_margin="20dp"
        android:background="@drawable/animationtk"
        android:gravity="center"
        android:text="点击弹出动画"
        android:textColor="#fff"
        android:textSize="18dp" />

2.activity代码、

package cll.com.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

/**
 *  @Description 奔跑小人的动画弹框，可以用作加载数据界面
 *  2017-4-3 http://blog.csdn.net/android_cll
 */
public class RuningManActivity extends Activity implements View.OnClickListener {

    private TextView textview;//点击按钮

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ac_runing_man);
        initlayout();
    }

    /**
     * 实例化
     */
    private void initlayout() {
        textview = (TextView) findViewById(R.id.textview);
        textview.setOnClickListener(this);
    }

    /**
     * 显示美团进度对话框
     *
     * @param v
     */
    public void showmeidialog(View v) {
        CustomProgressDialog dialog = new CustomProgressDialog(this, "正在加载中......", R.anim.animation);
        dialog.setCanceledOnTouchOutside(false);//设置是否可以点击外部消失
        dialog.setCancelable(false);//设置是否可以按退回键取消
        dialog.show();
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.textview:
                showmeidialog(view);
                break;
        }
    }
}

3.自定义弹框工具类、

package cll.com.myapplication;

import android.app.ProgressDialog;
import android.content.Context;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;

/**
 * @Description:自定义加载数据弹框
 * @author 2017-4-3 http://blog.csdn.net/android_cll
 */
public class CustomProgressDialog extends ProgressDialog {

   private AnimationDrawable mAnimation;
   private ImageView mImageView;
   private String mLoadingTip;
   private TextView mLoadingTv;
   private int mResid;

   public CustomProgressDialog(Context context, String content, int id) {
      super(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();
      // 为了防止在onCreate方法中只显示第一帧的解决方案之一
      mImageView.post(new Runnable() {
         @Override
         public void run() {
            mAnimation.start();

         }
      });
      mLoadingTv.setText(mLoadingTip);

   }

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

}

4.自定义弹框的xml布局、

xml version="1.0" encoding="utf-8"?>
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" >

            android:id="@+id/loadingIv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@anim/animation"/>

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

5.anim文件下 的帧动画文件

xml version="1.0" encoding="utf-8"?>  
    android:oneshot="false"
    xmlns:android="http://schemas.android.com/apk/res/android" 
    >   
    android:drawable="@mipmap/progress_loading_image" android:duration="150"/>
     android:drawable="@mipmap/progress_loading_imagey" android:duration="150"/>
   

-------------------------到此加载数据弹框的帧动画功能就实现了，不喜勿喷，都有注释就不用解释太多、
