如何在recyclerview中加载webview？

Question

我想在 recyclerview 中加载一个 webview。

我试过在默认浏览器中打开网页（比如 chrome）。

谁能帮我做一下？

Answer 1

从 Android 库继承 WebView：

import android.content.Context;
import android.util.AttributeSet;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;


public class MyWebView extends WebView {

  public MyWebView(Context context) {
    super(context);
    initDefaultSetting();
  }

  public MyWebView(Context context, AttributeSet attrs) {
    super(context, attrs);
    initDefaultSetting();
  }

  public MyWebView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    initDefaultSetting();
  }

  public MyWebView(Context context, AttributeSet attrs, int defStyleAttr,
      int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
    initDefaultSetting();
  }


  private void initDefaultSetting() {
    WebSettings webSettings = this.getSettings();
    webSettings.setJavaScriptEnabled(true);
    setWebChromeClient(new WebChromeClient());
    setWebViewClient(new MyWebViewClient());
  }

  /**
   * Load Web View with url
   */
  public void load(String url) {
    this.loadUrl(url);
  }

}

从库中继承并覆盖了 WebViewClient 的方法

Class: MyWebViewClient

public class MyWebViewClient extends WebViewClient {

  @Override
  public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
    view.loadUrl(request.getUrl().toString());
    return true;

  }
}

布局：row_my_web.xml

<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="300dp">

  <com.silicus.fluidforms.MyWebView
    android:id="@+id/myWebView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</FrameLayout>

Class: 父适配器

import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.silicus.fluidforms.MyWebView;
import com.silicus.fluidforms.R;
import com.silicus.fluidforms.expandable.ParentAdapter.MyViewHolder;


    public class ParentAdapter extends RecyclerView.Adapter<MyViewHolder> {


      private String urlList[] = {
          "",
          "https://developer.android.com/guide/webapps/webview",
          "https://www.google.com",
          "https://www.bling.com"};


      @NonNull
      @Override
      public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.row_my_web, parent, false);
        return new MyViewHolder(itemView);
      }

      @Override
      public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        holder.myWebView.load(urlList[position]);
      }

      @Override
      public int getItemCount() {
        return urlList.length;
      }

      class MyViewHolder extends RecyclerView.ViewHolder {

        MyWebView myWebView;

        MyViewHolder(View itemView) {
          super(itemView);
          myWebView = itemView.findViewById(R.id.myWebView);
        }
      }
    }

Answer 2

如果你的意思是不是加载页面而是显示弹出窗口询问你想如何打开 URL，你可以通过向网络视图添加 WebViewClient 来修复它

WebViewClient webViewClient = new WebViewClient();
webView.setWebViewClient(webViewClient);
