问题描述

在描述我更改日志的对话,我想有一些联系我们的Twitter和Facebook页面。因为我不想在文本裸网址,我使用 Html.fromHtml(..)和标准的HTML链接样式(A HREF)。但是,我不能得到的链接,可以点击,不管我怎么做的对话框(通过要么是AlertDialog.Builder或自定义视图对话框)。我还设置 linksClickable = TRUE 在TextView的,但没有运气。如果有人可以帮助我,那简直太好了!

change_log_dialog.xml

 < LinearLayout中的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
机器人:ID =@ + ID / linlay2
机器人:layout_width =match_parent
机器人:layout_height =match_parent
机器人:方向=垂直><的TextView
    机器人:ID =@ + ID / dialog_text_view
    机器人:layout_width =match_parent
    机器人:layout_height =0dip
    机器人:layout_margin =@扪/ view_padding
    机器人:layout_weight =1
    机器人:linksClickable =真
    机器人:文字=@字符串/ gen_placeholder
    机器人:textAppearance =机器人:ATTR / textAppearanceMedium>
< / TextView的><的LinearLayout
    机器人:ID =@ + ID / VerticalLayout的
    机器人:layout_width =match_parent
    机器人:layout_height =WRAP_CONTENT
    机器人:分=机器人:ATTR / dividerHorizo​​ntal
    机器人:dividerPadding =0dip
    机器人:方向=垂直
    机器人:showDividers =开始>    <按钮
        机器人:ID =@ + ID / help_close
        风格=机器人:ATTR / buttonBarButtonStyle
        机器人:layout_width =match_parent
        机器人:layout_height =WRAP_CONTENT
        机器人:文字=@字符串/ help_close/>< / LinearLayout中>

调用该对话框当前方法:

 对话对话框=新的对话框(本);
dialog.setTitle(R.string.changetitle);
视图V = getLayoutInflater()膨胀(R.layout.change_log_dialog,NULL);
((的TextView)v.findViewById(R.id.dialog_text_view))的setText(getRawAsset(R.raw.change));
dialog.setContentView(五);
返回对话框;

与getRawAsset(..):

 公共跨区getRawAsset(INT ID){    的InputStream Mstream工具= getResources()openRawResource(ID)。
    InputStreamReader的MREAD =新的InputStreamReader(Mstream工具);
    BufferedReader中的MReader =新的BufferedReader(MREAD);
    StringBuilder的回归者=新的StringBuilder();
    串线=;
    尝试{
        而((行= mReader.readLine())!= NULL){            returner.append(线);        }        返回Html.fromHtml(returner.toString());
    }赶上(IOException异常五){
        e.printStackTrace();
    }
    返回null;}


解决方案

也许你宁愿使用的的>而不是 Html.fromHtml(...) Linkify ,伴随着的,应该能够在链接转换为更具人性化。

In a dialog describing my change log, I'd like to have some links to our twitter and facebook pages. Because I don't want to have the bare urls in the text, I'm using Html.fromHtml(..) and standard html style links (a href). However, I can't get the links to be clickable, regardless of how I do the dialog (via either an AlertDialog.Builder or a Dialog with a custom view). I've also set linksClickable=true in the textview, but no luck. If anyone could help me, that'd be great!

change_log_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linlay2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/dialog_text_view"
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:layout_margin="@dimen/view_padding"
    android:layout_weight="1"
    android:linksClickable="true"
    android:text="@string/gen_placeholder"
    android:textAppearance="?android:attr/textAppearanceMedium" >
</TextView>

<LinearLayout
    android:id="@+id/verticallayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:divider="?android:attr/dividerHorizontal"
    android:dividerPadding="0dip"
    android:orientation="vertical"
    android:showDividers="beginning" >

    <Button
        android:id="@+id/help_close"
        style="?android:attr/buttonBarButtonStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/help_close" />

</LinearLayout>

current method for calling the dialog:

Dialog dialog = new Dialog(this);
dialog.setTitle(R.string.changetitle);
View v = getLayoutInflater().inflate(R.layout.change_log_dialog, null);
((TextView) v.findViewById(R.id.dialog_text_view)).setText(getRawAsset(R.raw.change));
dialog.setContentView(v);
return dialog;

with getRawAsset(..):

public Spanned getRawAsset(int id) {

    InputStream mStream = getResources().openRawResource(id);
    InputStreamReader mRead = new InputStreamReader(mStream);
    BufferedReader mReader = new BufferedReader(mRead);
    StringBuilder returner = new StringBuilder();
    String line = "";
    try {
        while ((line = mReader.readLine()) != null) {

            returner.append(line);

        }

        return Html.fromHtml(returner.toString());
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;

}
解决方案

Perhaps you would rather use Linkify instead of Html.fromHtml(...). Linkify, along with Linkify.TransformFilter, should be able to convert the links to something more user friendly.
