Android学习笔记--实现正在加载圆圈，加完完成自动取消

Posted 2020-08-15

今天学到了，网络加载数据 没加载之前是显示正在加载，加载之后 正在加载四个字消失不见，这里要用到一个自定义控件

TipInfoLayout.java  这个是自定义组件的代码 复制粘贴就好

  1 package com.wuxianedu.wxhlcorelibrary.widget;
  2 
  3 import android.content.Context;
  4 import android.util.AttributeSet;
  5 import android.view.LayoutInflater;
  6 import android.view.View;
  7 import android.widget.FrameLayout;
  8 import android.widget.ImageView;
  9 import android.widget.TextView;
 10 
 11 import com.pnikosis.materialishprogress.ProgressWheel;
 12 import com.wuxianedu.wxhlcorelibrary.R;
 13 
 14 public class TipInfoLayout extends FrameLayout {
 15     private ProgressWheel mPbProgressBar;
 16     public ImageView mTvTipState;
 17     private TextView mTvTipMsg;
 18 
 19     private Context context;
 20 
 21     public TipInfoLayout(Context context) {
 22         super(context);
 23         this.context = context;
 24         initView(context);
 25     }
 26 
 27     public TipInfoLayout(Context context, AttributeSet attrs) {
 28         super(context, attrs);
 29         this.context = context;
 30         initView(context);
 31     }
 32 
 33     public TipInfoLayout(Context context, AttributeSet attrs, int defStyleAttr) {
 34         super(context, attrs, defStyleAttr);
 35         this.context = context;
 36         initView(context);
 37     }
 38 
 39     private void initView(Context context) {
 40         View view = LayoutInflater.from(context).inflate(R.layout.core_tip_info_layout, null, false);
 41         mPbProgressBar = (ProgressWheel) view.findViewById(R.id.tv_tip_loading);
 42         mTvTipState = (ImageView) view.findViewById(R.id.tv_tip_state);
 43         mTvTipMsg = (TextView) view.findViewById(R.id.tv_tip_msg);
 44         setLoading();
 45 //        completeLoading();
 46         addView(view);
 47     }
 48 
 49     /*public void setOnClick(OnClickListener onClik) {
 50         this.setOnClickListener(onClik);
 51     }*/
 52 
 53     public void setLoading() {
 54         setLoading(context.getString(R.string.tip_loading));
 55     }
 56 
 57     public void setLoading(String message) {
 58         //this.setVisibility(VISIBLE);
 59         this.mPbProgressBar.setVisibility(View.VISIBLE);
 60         this.mTvTipState.setVisibility(View.GONE);
 61         this.mTvTipMsg.setVisibility(View.VISIBLE);
 62         this.mTvTipMsg.setText(context.getString(R.string.tip_loading));
 63     }
 64 
 65     /**
 66      * 完成加载
 67      */
 68     public void completeLoading(){
 69         this.mPbProgressBar.setVisibility(View.GONE);
 70         this.mTvTipState.setVisibility(View.GONE);
 71         this.mTvTipMsg.setVisibility(View.GONE);
 72     }
 73 
 74     public void setNetworkError() {
 75         this.mPbProgressBar.setVisibility(View.GONE);
 76         this.mTvTipState.setVisibility(View.VISIBLE);
 77         this.mTvTipState.setImageResource(R.drawable.core_page_icon_network);
 78         this.mTvTipMsg.setVisibility(View.VISIBLE);
 79         this.mTvTipMsg.setText(context.getString(R.string.tip_load_network_error));
 80     }
 81 
 82     public void setLoadError(String message){
 83         setLoadError();
 84         this.mTvTipMsg.setText(message);
 85     }
 86 
 87     public void setLoadError() {
 88         this.mPbProgressBar.setVisibility(View.GONE);
 89         this.mTvTipState.setVisibility(View.VISIBLE);
 90         this.mTvTipState.setImageResource(R.drawable.core_page_icon_loaderror);
 91         this.mTvTipMsg.setVisibility(View.VISIBLE);
 92         this.mTvTipMsg.setText(context.getString(R.string.tip_load_error));
 93     }
 94 
 95     public void setEmptyData(String message){
 96         setEmptyData();
 97         this.mTvTipMsg.setText(message);
 98     }
 99 
100     public void setEmptyData() {
101         this.setVisibility(VISIBLE);
102         this.mPbProgressBar.setVisibility(View.GONE);
103         this.mTvTipState.setVisibility(View.VISIBLE);
104         this.mTvTipState.setImageResource(R.drawable.core_page_icon_empty);
105         this.mTvTipMsg.setVisibility(View.VISIBLE);
106         this.mTvTipMsg.setText(context.getString(R.string.tip_load_empty));
107     }
108 
109     /**
110      * 不显示任何提示
111      */
112     public void setCancelShow(){
113         this.mPbProgressBar.setVisibility(View.GONE);
114         this.mTvTipState.setVisibility(View.GONE);
115         this.mTvTipMsg.setVisibility(View.GONE);
116     }
117 }

之后我们在布局里面用到它

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent">
 5 
 6     <com.wuxianedu.wxhlcorelibrary.widget.RefreshLayout
 7         android:id="@+id/refreshLayout"
 8         android:layout_width="wrap_content"
 9         android:layout_height="wrap_content">
10         <ListView android:id="@+id/lv_liebiao"
11             android:layout_width="match_parent"
12             android:layout_height="match_parent" />
13     </com.wuxianedu.wxhlcorelibrary.widget.RefreshLayout>
14  <com.wuxianedu.wxhlcorelibrary.widget.TipInfoLayout
15      android:id="@+id/tipInfoLayout_id"
16      android:layout_width="match_parent"
17      android:layout_height="match_parent"/>
18 
19 
20 </RelativeLayout>

之后在java文件中初始化他

1 tipInfoLayout = (TipInfoLayout) view.findViewById(R.id.tipInfoLayout_id);

//开始加载
tipInfoLayout.setLoading();
//完成加载

tipInfoLayout.completeLoading();
