Question

我从JSON获取数据并以RecyclerView布局显示。我的textview显示整个链接。例如，我的TextView是安装的，链接是alerts。在RecyclerView中，它应该只显示http://mydomin.com?id=2054656文本，当它被点击时，应该转到URL。我试过下面的代码。

install

它工作正常，但显示整个链接而不是文本。我希望你明白。

将textview更改为按钮后，请查看我的完整代码

Viewholder.ImageUrlNameView.setText(getDataAdapter1.getImageUrlName());

ImageUrlNameView = (TextView) itemView.findViewById(tvAppLink) ;

ImageUrlNameView.setMovementMethod(LinkMovementMethod.getInstance());

通过这种方式将点击逻辑更改为onBindViewHolder，您拥有当前对象的网址：

 @Override
        public void onBindViewHolder(ViewHolder Viewholder, int position) {

            GetDataAdapter getDataAdapter1 =  getDataAdapter.get(position);

            imageLoader1 = ServerImageParseAdapter.getInstance(context).getImageLoader();

            imageLoader1.get(getDataAdapter1.getImageServerUrl(),
                    ImageLoader.getImageListener(
                            Viewholder.networkImageView,//Server Image
                            R.mipmap.ic_launcher,//Before loading server image the default showing image.
                            android.R.drawable.ic_dialog_alert //Error image if requested image dose not found on server.
                    )
            );

            Viewholder.networkImageView.setImageUrl(getDataAdapter1.getImageServerUrl(), imageLoader1);

            Viewholder.ImageTitleNameView.setText(getDataAdapter1.getImageTitleName());

            Viewholder.ImageUrlNameView.setText("Install");



Viewholder.ImageUrlNameView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        String url = getDataAdapter1.getImageUrlName();

                        Intent intent = new Intent(Intent.ACTION_VIEW);
                        intent.setData(Uri.parse(url));
                        context.startActivity(intent);
                    }
                });

        }

        @Override
        public int getItemCount() {

            return getDataAdapter.size();
        }

        class ViewHolder extends RecyclerView.ViewHolder{

            public NetworkImageView networkImageView ;
            public TextView ImageTitleNameView;
            public Button ImageUrlNameView ;

            public ViewHolder(View itemView) {

                super(itemView);

                networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1) ;
                ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item);
                ImageUrlNameView = (Button) itemView.findViewById(R.id.bAppUrl) ;
                //ImageUrlNameView.setMovementMethod(LinkMovementMethod.getInstance());
                //Linkify.addLinks(ImageUrlNameView, Linkify.WEB_URLS);




            }


        }

Answer 2

方法1： 尝试这对我有用 - 1） String installString =“install”; String hyperlinkString =“Whatever string”+ installString +“text”; SpannableString hyperlinkText = makeHyperlinkText（hyperlinkString，installString）; textView.setText（hyperlinkText）; textView.setMovementMethod（LinkMovementMethod.getInstance（））;

2）功能在这里：

private SpannableString makeHyperlinkText(String hyperlinkString, String textToMakeHyperlink) {
        SpannableString content = new SpannableString(hyperlinkString);
        ClickableSpan clickableSpan = new ClickableSpan() {
            @Override
            public void onClick(View widget) {
                Intent webviewIntent = new Intent(YourCurrentActivity.this, WebviewActivity.class);
                webviewIntent.putExtra("URL", your_url_here); //EDIT
                startActivity(webviewIntent);
                }
            };
            int startIndex = hyperlinkString.indexOf(textToMakeHyperlink);
            int endIndex = startIndex + textToMakeHyperlink.length();
            content.setSpan(clickableSpan, startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            return content;
    }

//编辑：在

下添加这些文件

3）WebviewActivity类在这里 -

public class WebviewActivity extends AppCompactActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_webview_layout);

        String url = getIntent().getStringExtra("URL");

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        WebView myWebView = (WebView) findViewById(R.id.webview);
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        myWebView.loadUrl(url);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onBackPressed();
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

4）Webview Layour类（根据需要自定义）：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.massmutual.css.ui.loan.LoanDisclosureWebView">

    <WebView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</RelativeLayout>

方法2： 您可以更改传递url字符串的方式。它需要是HTML格式。例如：

<a href="www.google.com">Click here for google.</a>

所以我认为你的文字会是这样的：

    String url = "http://mydomin.com?id=2054656";
    String text = "install";
    String hyperlinkText = "<a href=\"" + url + "\""> + text + "</a>";

让我知道这些是否适合您。
