android - ProgressDialog 旋转圈

Question

我想像这样实现 ProgressDialog，没有额外的框架：

但我得到了这个。我怎么能改变呢？

在此处输入图像描述

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();
            }
        }

只需从布局更改ProgressDialog为：ProgressBar

资源/布局.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>

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ProgressBar我用来更改默认颜色的自定义。

<?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>

把这个 XML 只显示轮子：

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

我正在使用View.INVISIBLEandView.VISIBLE并且ProgressBar会慢慢闪烁而不是一直可见，切换到View.GONEandView.VISIBLE并且它工作得很好

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();
    }

}

R.layout.dialog_api_loading

  <androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:cardCornerRadius="@dimen/size_10">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:orientation="horizontal"
        android:padding="20dp">
<ProgressBar
            android:layout_width="@dimen/size_20"
            android:layout_height="@dimen/size_20" />
            <TextView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_marginHorizontal="@dimen/txt_distance_5"
            android:gravity="center"
            android:text="Loading..." />
    </LinearLayout>
</androidx.cardview.widget.CardView>
