安卓系統(tǒng)自己的加載動畫太簡單了,長時間后會造成視覺疲勞,所以有時候需要定義一些有趣的動畫,也因為我們通常專注于業(yè)務和性能處理,接下來武林技術(shù)頻道小編為大家?guī)?a target="_blank">Android自定義加載控件實現(xiàn)數(shù)據(jù)加載動畫,一起來看看吧!

package com.*****.*****.widget; import android.content.Context;import android.graphics.drawable.AnimationDrawable;import android.util.AttributeSet;import android.view.LayoutInflater;import android.view.View;import android.widget.ImageView;import android.widget.RelativeLayout;import android.widget.TextView; /** * Created by Xiaomu * 數(shù)據(jù)加載控件 */public class LoadingView extends RelativeLayout { private Context mContext; private ImageView loadingIv; private TextView loadingTv; public LoadingView(Context context) { super(context); this.mContext = context; initView(); } public LoadingView(Context context, AttributeSet attrs) { super(context, attrs); this.mContext = context; initView(); } private void initView() { View view = LayoutInflater.from(mContext).inflate(R.layout.loading, null); loadingIv = (ImageView) view.findViewById(R.id.loadingIv); loadingTv = (TextView) view.findViewById(R.id.loadingTv); AnimationDrawable animationDrawable = (AnimationDrawable) loadingIv.getBackground(); if (animationDrawable != null) animationDrawable.start(); addView(view); } public ImageView getLoadingIv() { return loadingIv; } public TextView getLoadingTv() { return loadingTv; }}2. xml布局文件????
<?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="wrap_content"> <ImageView android:id="@+id/loadingIv" android:layout_width="@dimen/dimen_144_dip" android:layout_height="@dimen/dimen_162_dip" android:layout_centerHorizontal="true" android:background="@anim/loading_anim" /> <TextView android:id="@+id/loadingTv" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignBottom="@+id/loadingIv" android:layout_centerHorizontal="true" android:gravity="center_horizontal" android:text="正在加載中..." android:textSize="15sp" /> </RelativeLayout>
3. loading_anim加載動畫的xml????
<?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>
看了上面的介紹,相信大家對于Android自定義加載控件實現(xiàn)數(shù)據(jù)加載動畫,已經(jīng)有了自己的認識,武林技術(shù)頻道為大家提供更多知識,希望幫到您。
