A simple custom prompt box dialog

The main structure is very simple and will not be explained separately

package com.mj.regist;

import android.app.ProgressDialog;
import android.content.Context;
import android.os.Bundle;
import android.view.WindowManager;


public class Loading_view extends ProgressDialog {
    public Loading_view(Context context) {
        super(context);
    }

    public Loading_view(Context context, int theme) {
        super(context, theme);
    }

    @Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    

        init(getContext());
    }

    private void init(Context context) {
        setCancelable(true);
        setCanceledOnTouchOutside(false);

        setContentView(R.layout.pro_dialog);//loading的xml文件
        WindowManager.LayoutParams params = getWindow().getAttributes();
        params.width = WindowManager.LayoutParams.WRAP_CONTENT;
        params.height = WindowManager.LayoutParams.WRAP_CONTENT;
        getWindow().setAttributes(params);
    }

    @Override
public void show() {//开启
super.show();            
    }

    @Override
public void dismiss() {//关闭
super.dismiss();            
    }
}

The corresponding layout file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerInParent="true"
android:layout_gravity="center_horizontal"
android:background="@drawable/pro_shape"
android:orientation="vertical">                        

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp">

        <ProgressBar
            android:id="@+id/pb_load"
            android:layout_width="65dp"
            android:layout_height="65dp"
            android:layout_centerInParent="true"
            android:indeterminateDrawable="@drawable/pro_dilogstlr" />

    </RelativeLayout>

    <TextView
android:id="@+id/tv_load_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="加载中..."
android:textColor="#9a9b98"
android:textSize="12sp" />                                                        

</LinearLayout>

Corresponding shap attribute: under the Drawable path

  pro_dilogstlr.xml

<animated-rotate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%"
    android:fromDegrees="0"
    android:toDegrees="720">

    <shape
        android:shape="ring"
        android:innerRadiusRatio="3"
        android:thicknessRatio="15"
        android:useLevel="false">
        <gradient
android:type="sweep"
android:useLevel="false"
android:startColor="#55c6c6c6"
android:centerColor="#c6c6c6"
android:centerY="0.50"
android:endColor="#c6c6c6" />                                                                        
    </shape>

</animated-rotate>

pro_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <corners android:radius="8dp" />
    <solid android:color="#88000000" />
</shape>

调用：

private void  showDialog(){
    loading = new Loading_view(this,R.style.CustomDialog);
    loading.show();

}
private void  dismisDialog(){
    loading.dismiss();//3秒后调用关闭加载的方法
}
