Android之仿美团加载数据帧动画
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"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView 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" /> </RelativeLayout>
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"?> <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/animation"/> <TextView 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.." /> </RelativeLayout>
5.anim文件下的帧动画文件
<?xml version="1.0" encoding="utf-8"?> <animation-list android:oneshot="false" xmlns:android="http://schemas.android.com/apk/res/android" > <item android:drawable="@mipmap/progress_loading_image" android:duration="150"/> <item android:drawable="@mipmap/progress_loading_imagey" android:duration="150"/> </animation-list>
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
