自定义加载Dialog

效果图

1,对话框封装类

public class DialogUtils {
    public static Dialog createLoadingDialog(Context context, String msg) {
        LayoutInflater inflater = LayoutInflater.from(context);
        View v = inflater.inflate(R.layout.dialog_loading, null);// 得到加载view
        LinearLayout layout = (LinearLayout) v.findViewById(R.id.dialog_loading_view);// 加载布局
        TextView tipTextView = (TextView) v.findViewById(R.id.tipTextView);// 提示文字
        tipTextView.setText(msg);// 设置加载信息rotate_animationrotate_animation

        Dialog loadingDialog = new Dialog(context, R.style.MyDialogStyle);// 创建自定义样式dialog
        loadingDialog.setCancelable(true); // 是否可以按“返回键”消失
        loadingDialog.setCanceledOnTouchOutside(false); // 点击加载框以外的区域
        loadingDialog.setContentView(layout, new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.MATCH_PARENT));// 设置布局
        /**
         *将显示Dialog的方法封装在这里面
         */
        Window window = loadingDialog.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        window.setGravity(Gravity.CENTER);
        window.setAttributes(lp);
        window.setWindowAnimations(R.style.PopWindowAnimStyle);
        loadingDialog.show();

        return loadingDialog;
    }

    /**
     * 关闭dialog
     * <p>
     *
     * @param mDialogUtils
     */
    public static void closeDialog(Dialog mDialogUtils) {
        if (mDialogUtils != null && mDialogUtils.isShowing()) {
            mDialogUtils.dismiss();
        }
    }
}

2,布局文件dialog_loading.xml代码

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

        android:paddingBottom="10dp"
        android:paddingLeft="21dp"
        android:paddingRight="21dp"
        android:paddingTop="10dp">

        <ProgressBar
            android:id="@+id/progressBar1"
            android:layout_width="35dp"
            android:layout_height="35dp"
            android:layout_gravity="center_horizontal"
            android:indeterminateBehavior="repeat"
            android:indeterminateDrawable="@drawable/dialog_loading"
            android:indeterminateOnly="true" />

        <TextView
            android:id="@+id/tipTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dp"
            android:text="加载中..."
            android:textColor="#f0f0f0"
