ProgressDialog旋转圈

Question

我想像这样实现ProgressDialog，没有额外的框架：

但是我得到了这个。我怎么能改变呢？

这是我的ProgressDialog代码。 提前致谢

private ProgressDialog mProgressDialog;
   ............
   mProgressDialog = new ProgressDialog(activity);
   mProgressDialog.setIndeterminate(false);
   mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
   ............
    public class ProgressTask extends AsyncTask <Fragment,Void,Fragment>{
            @Override
            protected void onPreExecute(){
                mProgressDialog.show();
            }

            @Override
            protected Fragment doInBackground(Fragment... arg0) {   
                    //my stuff is here
            }

            @Override
            protected void onPostExecute(Fragment result) {
                   mProgressDialog.dismiss();
            }
        }

只需在布局中从ProgressDialog更改为ProgressBar：

<强> RES / layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        //Your content here
     </LinearLayout>

        <ProgressBar
            android:id="@+id/progressBar"
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:visibility="gone"
            android:indeterminateDrawable="@drawable/progress" >
        </ProgressBar>
</RelativeLayout>

<强>的src / yourPackage / YourActivity.java

public class YourActivity extends Activity{

private ProgressBar bar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout);
    bar = (ProgressBar) this.findViewById(R.id.progressBar);
    new ProgressTask().execute();
}
private class ProgressTask extends AsyncTask <Void,Void,Void>{
    @Override
    protected void onPreExecute(){
        bar.setVisibility(View.VISIBLE);
    }

    @Override
    protected Void doInBackground(Void... arg0) {   
           //my stuff is here
    }

    @Override
    protected void onPostExecute(Void result) {
          bar.setVisibility(View.GONE);
    }
}
}

drawable / progress.xml 这是我用来更改默认颜色的自定义ProgressBar。

<?xml version="1.0" encoding="utf-8"?>

<!-- 
    Duration = 1 means that one rotation will be done in 1 second. leave it.
    If you want to speed up the rotation, increase duration value. 
    in example 1080 shows three times faster revolution. 
    make the value multiply of 360, or the ring animates clunky 
-->
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:duration="1"
    android:toDegrees="360" >

    <shape
        android:innerRadiusRatio="3"
        android:shape="ring"
        android:thicknessRatio="8"
        android:useLevel="false" >
        <size
            android:height="48dip"
            android:width="48dip" />

        <gradient
            android:centerColor="@color/color_preloader_center"
            android:centerY="0.50"
            android:endColor="@color/color_preloader_end"
            android:startColor="@color/color_preloader_start"
            android:type="sweep"
            android:useLevel="false" />
    </shape>

</rotate>

将此XML仅显示轮子：

<ProgressBar
    android:indeterminate="true"
    android:id="@+id/marker_progress"
    style="?android:attr/progressBarStyle"
    android:layout_height="50dp" />

Answer 3

我正在使用View.INVISIBLE和View.VISIBLE而ProgressBar会慢慢闪烁而不是一直可见，切换到View.GONE和View.VISIBLE并且它完美运行

ProgressBar Dialog - 无需一直编写自定义 progressBar 代码，创建一个下面的类并使用

public class DProgressbar {
    Dialog progressDialog ;
    public DProgressbar(Context context) {
        progressDialog = new Dialog(context);
        progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        progressDialog.setContentView(R.layout.dialog_api_loading);
        progressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        progressDialog.setCancelable(false);
    }

    public void show(){
        progressDialog.show();
    }

    public void dismiss(){
        progressDialog.dismiss();
    }

}

试试这个.........

ProgressDialog pd1;
pd1=new ProgressDialog(<current context reference here>);
pd1.setMessage("Loading....");
pd1.setCancelable(false);
pd1.show();

解雇......

if(pd1!=null)
 pd1.dismiss();
