使用webview 时报错：Cannot start http server for devtools. Stop devtools.

少年加上这几行代码 完美运行

WebSettings webSettings = mWebView.getSettings();
        // 设置与Js交互的权限
        webSettings.setJavaScriptEnabled(true);
        webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        mWebView.loadUrl("https://www.baidu.com/");

针对问题 补充 自定义 WebView

import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.webkit.WebView;

    public NoScrollWebView(Context context, AttributeSet attrs, int defStyleAttr) {

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int mExpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, mExpandSpec);
    }
