### 自定义View完成网络加载时提示的Diaglog ###

public class LoadDialog extends Dialog {
        
    
        private LinearLayout linearLayout;
        private ProgressBar mBar;
        private TextView mTv;
    
        public LoadDialog(@NonNull Context context) {
        
            super(context);
            //点击外部不消失
            setCancelable(false);
            getWindow().setDimAmount(0);
            getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            getWindow().setContentView(initView());
        }
    
        private LinearLayout initView() {
        
            //设置父容器
            linearLayout = new LinearLayout(getContext());
            linearLayout.setOrientation(LinearLayout.VERTICAL);
            linearLayout.setGravity(Gravity.CENTER_VERTICAL);
            linearLayout.setBackgroundResource(R.drawable.dialog_bg);
            linearLayout.setAlpha(0.5f);
    
            //初始化子控件
            LinearLayout.LayoutParams tvParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,0);
            tvParams.gravity = Gravity.CENTER;
            tvParams.weight = 2;
    
            LinearLayout.LayoutParams barParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,0);
            barParams.gravity = Gravity.CENTER;
            barParams.weight = 8;
    
            mBar = new ProgressBar(getContext());
            mBar.setLayoutParams(barParams);
    
            mTv = new TextView(getContext());
            mTv.setText("正在加载,请稍候...");
            mTv.setTextColor(Color.BLACK);
            mTv.setGravity(Gravity.CENTER);
    
            //添加到父容器
            linearLayout.addView(mBar);
            linearLayout.addView(mTv);
    
            return linearLayout;
        }
    }

使用

LoadDialog loadDialog = new LoadDialog(this);
    loadDialog.show();
