ProgressBar---进度条

最近在处理标题进度条时，耗费了一些时间，现在总结一下ProgressBar的相关知识，有不对的地方请大神们批评指正！

进度条主要有以下三种：

1.对话框进度条

2.标题进度条

注意：requestWindowFeature(),setContentView(),setProgressBarIndeterminateVisibility()的先后位置

AndroidManifest.xml文件中android:theme="@style/AppTheme，这种style下action(标题)不显示

3.自定义进度条

以下是具体的代码实现

ProgressBarActivity.class

/**
 * 1.对话框进度条
 * 2.标题进度条
 * 3.自定义进度条
 */
public class ProgressBarActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //标题进度条(注意requestWindowFeature()与setProgressBarVisibility()的位置)
        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
        setContentView(R.layout.activity_progress_bar);

        setProgressBarIndeterminateVisibility(true);
    }

    /**
     * 显示对话框进度条
     * @param view
     */
    public void dialogProgressBar(View view){
        //方法一:创建对话框
        /*ProgressDialog pb = new ProgressDialog(this);
        pb.setMax(100);
        pb.setProgress(50);
        pb.setCancelable(true);//是否可以被取消
        pb.setTitle("下载对话框");
        pb.setMessage("正在下载中....");
        pb.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pb.show();*/

        //方法二:创建对话框(比方法一更简洁)
        ProgressDialog pb1 = ProgressDialog.show(this,"downLoad","downLoading....",false);

    }
}

　　AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.langdon.taiyang.androidtest">

    <application
        android:allowBackup="true"

activity_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

</LinearLayout>

　　

progress_bg.xml---自定义进度条的旋转效果

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <rotate android:drawable="@drawable/progress" android:fromDegrees="0"
            android:toDegrees="360" android:pivotX="50%" android:pivotY="50%">

        </rotate>
    </item>
</selector>

效果图如下：
