Question

我写了一个在对话框中打开webView的函数，问题是当我点击textArea时键盘没有弹出我尝试了this线程中的所有解决方案无济于事

此代码在android.support.v4.app.Fragment

中起作用

    public void openWebView() {
        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this.getActivity());
        WebView webView = new WebView(this.getActivity());
        webView.loadUrl("http://www.google.com");
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);

                return true;
            }
        });
        alertBuilder.setView(webView);
        webView.getSettings().setJavaScriptEnabled(true);
        alertBuilder.show();
}

当我按下文本区域几次时，这是日志：

        09-15 11:44:56.165  27483-27542/ngapps.socialbackground D/webcoreglue﹕ WebViewCore::nextTextOrSelectNode :  nextNode is NULL

您可以像这样定义假键盘：

 AlertDialog.Builder alert = new AlertDialog.Builder(this); 
            WebView wv = new WebView(this);
            LinearLayout wrapper = new LinearLayout(this);
            EditText keyboardHack = new EditText(this);
            keyboardHack.setVisibility(View.GONE);
            wv.getSettings().setJavaScriptEnabled(true);
            wv.loadUrl(loadUrl);
            wv.setWebViewClient(new WebViewClient() {
                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    view.loadUrl(url);

                    return true;
                }
            });

            wrapper.setOrientation(LinearLayout.VERTICAL);
            wrapper.addView(wv, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
            wrapper.addView(keyboardHack, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);              
            alert.setView(wrapper);

警报生成器内的webview，键盘不会弹出
