加油!

 

一、普通的ProgressBar
显示如图

<ProgressBar
        android:id="@+id/pbNormal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

二、有进度的ProgressBar

 

 

xml:设置style,Horizontal
<ProgressBar
       android:id="@+id/progress"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       style="@style/Widget.AppCompat.ProgressBar.Horizontal"
       />
设置进度java文件
        final ProgressBar  bar= (ProgressBar) findViewById(R.id.progress);
        final TextView textView= (TextView) findViewById(R.id.tvProgress);
        new Thread(){
            @Override
            public void run() {
                int i=0;
                while(i<100){
                    i++;
                    try {
                        Thread.sleep(80);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    final int j=i;
                    bar.setProgress(i);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            textView.setText(j+"%");
                        }
                    });
                }
            }
        }.start();

三、自定义有进度ProgressBar
 
progressBar进度条有两个部分组成,背景图形加载进度图形,使用<layer-list>标签,分别用backgroundprogress作为两个部分的id值,背景图形使用<shape>加载进度图形还需要用<clip>标签对图形<shape>标签进行包裹;

 

res下的drawable文件夹下,创建样式
custom_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape android:shape="rectangle">
        <corners android:radius="5dp"/>
        <gradient android:startColor="#fff"
                  android:endColor="#fff"/>
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip><!--可裁剪对象-->
            <shape android:shape="rectangle">
            <corners android:radius="5dp"/>
            <gradient android:angle="45" 
                      android:startColor="#f00"
                      android:endColor="#f90"/>
            </shape>
        </clip>
    </item>
</layer-list>
布局xml,需要指定ProgressBar的style
    <ProgressBar
        android:id="@+id/progressSelf"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        style="@style/Widget.AppCompat.ProgressBar.Horizontal"
        android:progressDrawable="@drawable/custom_progress"
        />
    <TextView
        android:id="@+id/tvProgress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
设置进度java文件
        final ProgressBar bar = (ProgressBar) findViewById(R.id.progressSelf);
        final TextView textView= (TextView) findViewById(R.id.tvProgress);
        new Thread(){
            @Override
            public void run() {
                int i=0;
                while(i<100){
                    i++;
                    try {
                        Thread.sleep(80);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    final int j=i;
                    bar.setProgress(i);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            textView.setText(j+"%");
                        }
                    });
                }
            }
        }.start();
