我在应用程序中使用自定义进度对话框。如下图所示,我要编辑两件事:首先,删除圆圈后面出现的黑色背景;其次,增加圆圈的体积并更改其颜色。
这是风格
<style name="CustomDialog" parent="@android:style/Theme.Dialog">
<item name="android:textColor">#FF4081</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:background">@android:color/transparent</item>
<item name="android:windowFrame">@android:color/transparent</item>
</style>
这是我的代码
dialog = new ProgressDialog(activity.this,R.style.CustomDialog);
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.show();
最佳答案
不推荐使用ProgressDialog。您可以使用警报对话框创建自定义进度对话框。
public static AlertDialog showProgressBar(Context context){
AlertDialog.Builder builder = new AlertDialog.Builder(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
@SuppressLint("InflateParams") View view = inflater.inflate(R.layout.layout_custom_progress_bar, null);
builder.setView(view);
AlertDialog dialog = builder.create();
dialog.show();
return dialog;
}
然后,您可以实例化该对话框,以便手动将其关闭。像这样使用它。
AlertDialog dialog = showProgressBa(this); // this will automatically show the custom progress bar
// to dismiss
dialog.dismiss();
这是进度对话框的自定义布局。
//layout_custom_progress_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<ProgressBar
android:id="@+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginStart="16dp"
android:indeterminateDrawable="@drawable/progress_bar"
android:max="100"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
您的进度条可绘制。您可以通过更改
android:centerColor android:endColor android:startColor
的值来更改颜色// progress_bar
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="200"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="1080" >
<shape
android:innerRadius="18dp"
android:shape="ring"
android:thickness="4dp"
android:useLevel="false" >
<size
android:height="48dp"
android:width="48dp" />
<gradient
android:centerColor="@color/colorPrimary"
android:centerY="0.5"
android:endColor="@color/colorWhite"
android:startColor="@color/colorPrimary"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
