如何使复选框文本的一部分可点击? [英] How do I make a portion of a Checkbox's text clickable?

问题描述

我正在尝试在文本框的相邻文本中创建链接.但是，此链接不是 URL，而是应充当按钮，以便我可以在 onItemClick 事件中执行一些任务.我基本上将其连接到显示我们的最终用户许可协议(硬编码)的视图.

我怎样才能做到这一点?

提前致谢.

解决方案

实际上有一个优雅的解决方案，使用 CheckBox 和单个 TextView.连同 TextView.setClickable()、Intent Filter 和 TextView.setMovementMethod() 的组合.

你有主视图(在这里，我称之为ClickableTextViewExample):

package id.web.freelancer.example;导入 android.app.Activity;导入 android.os.Bundle;导入 android.text.Html;导入 android.text.method.LinkMovementMethod;导入 android.widget.CheckBox;导入 android.widget.TextView;公共类 ClickableTextViewExampleActivity 扩展 Activity {/** 在第一次创建活动时调用.*/@覆盖public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);CheckBox 复选框 = (CheckBox)findViewById(R.id.checkBox1);TextView textView = (TextView)findViewById(R.id.textView2);checkbox.setText("");textView.setText(Html.fromHtml("我已阅读并同意" +"<a href='id.web.freelancer.example.TCActivity://Kode'>条款和条件</a>"));textView.setClickable(true);textView.setMovementMethod(LinkMovementMethod.getInstance());}}

ma​​in.xml

<线性布局android:id="@+id/linearLayout1"android:layout_width="match_parent"android:layout_height="wrap_content" ><复选框android:id="@+id/checkBox1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="CheckBox"/><文本视图android:id="@+id/textView2"android:layout_width="wrap_content"android:layout_height="wrap_content"机器人:文本=文本视图"android:clickable="true"/></LinearLayout></LinearLayout>

TCActivity.java

package id.web.freelancer.example;导入 android.app.Activity;导入 android.os.Bundle;公共类 TCActivity 扩展了 Activity {@覆盖public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.tc);}}

tc.xml

<文本视图android:id="@+id/tcView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="条款和条件"/></LinearLayout>

以及将这一切粘合在一起的最后一段代码，AndroidManifest.xml:

<意图过滤器><category android:name="android.intent.category.DEFAULT"/><action android:name="android.intent.action.VIEW"/><data android:scheme="id.web.freelancer.example.TCActivity"/></意图过滤器></活动>

来了，解释:

textView.setText(Html.fromHtml("我已阅读并同意" +"<a href='id.web.freelancer.example.TCActivity://Kode'>条款和条件</a>"));textView.setClickable(true);textView.setMovementMethod(LinkMovementMethod.getInstance());

<块引用>

setClickable 将允许您点击 textView.但不是 HREF 链接.为此，您必须使用 setMovementMethod() 并将其设置为 LinkMovementMethod.

之后，您需要捕获 URL.我使用 AndroidManifest.xml

中的 intent-filter 做到了这一点

<data android:scheme="id.web.freelancer.example.TCActivity"/>

<块引用>

它捕获 VIEW 命令，它只过滤以 id.web.freelancer.example.TCActivity://

开头的 URL

这是供您试用的软件包 和 这里是 github 存储库.希望这有帮助

I'm trying to create a link in my textbox's adjacent text. This link however is not a URL, but should act as a button so that I can perform a few tasks in the onItemClick event. I'm basically connecting this to a view that shows our End User License Agreement (hard coded).

How can I accomplish this?

Thanks in advance.

解决方案

There actually is an elegant solution, using CheckBox and single TextView. Along with a combinations of TextView.setClickable(), Intent Filter, and TextView.setMovementMethod().

You have main view (here, I called it ClickableTextViewExample):

package id.web.freelancer.example;

import android.app.Activity;
import android.os.Bundle;
import android.text.Html;
import android.text.method.LinkMovementMethod;
import android.widget.CheckBox;
import android.widget.TextView;

public class ClickableTextViewExampleActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        CheckBox checkbox = (CheckBox)findViewById(R.id.checkBox1);
        TextView textView = (TextView)findViewById(R.id.textView2);

        checkbox.setText("");
        textView.setText(Html.fromHtml("I have read and agree to the " +
                "<a href='id.web.freelancer.example.TCActivity://Kode'>TERMS AND CONDITIONS</a>"));
        textView.setClickable(true);
        textView.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <CheckBox
            android:id="@+id/checkBox1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="CheckBox" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView"
            android:clickable="true" />

    </LinearLayout>

</LinearLayout>

TCActivity.java

package id.web.freelancer.example;

import android.app.Activity;
import android.os.Bundle;

public class TCActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tc);
    }

}

tc.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

        <TextView
        android:id="@+id/tcView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Terms and conditions" />


</LinearLayout>

and the final piece of codes that glue it all, the AndroidManifest.xml:

<activity android:name="TCActivity">
    <intent-filter>
        <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="id.web.freelancer.example.TCActivity" />  
    </intent-filter>            
</activity>

Here comes, the explanations:

textView.setText(Html.fromHtml("I have read and agree to the " +
                     "<a href='id.web.freelancer.example.TCActivity://Kode'>TERMS AND CONDITIONS</a>"));
textView.setClickable(true);
textView.setMovementMethod(LinkMovementMethod.getInstance());

setClickable will allow you to click on textView. But not the HREF link. To do that, you will have to use setMovementMethod() and set it to LinkMovementMethod.

After that, you need to catch the URL. I did this using intent-filter in AndroidManifest.xml

<action android:name="android.intent.action.VIEW" />
<data android:scheme="id.web.freelancer.example.TCActivity" />  

It catch VIEW command and it only filter URL starting with id.web.freelancer.example.TCActivity://

Here's the package for you to try it out and here's the github repository. Hope this helped
