Question

我使用列表视图和Firebase进行了Android聊天。我想在聊天消息中激活链接。链接在message_text textview的文本中采用不同的格式。我怎么能活跃他们？

我的代码：

item_in_message.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/bubble_in">

<TextView
    android:id="@+id/message_user"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:text="fdsfsdf"
    android:textStyle="normal|bold" />

<TextView
    android:id="@+id/message_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/message_user"
    android:layout_marginTop="5dp"
    android:text="dsfsdfds"
    android:textAppearance="@style/TextAppearance.AppCompat.Body1"
    android:textColor="@android:color/white"
    android:textSize="18sp" />

<TextView
    android:id="@+id/message_time"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/message_text"
    android:text="sdfsdfsd" />

item_out_message.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:background="@drawable/bubble_out">

    <TextView
        android:id="@+id/message_user"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="fdsfsdf"
        android:textStyle="normal|bold" />

    <TextView
        android:id="@+id/message_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

    <TextView
        android:id="@+id/message_time"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

Answer 2

您需要制作列表视图基本适配器实现

例如

listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public boolean onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //here you can use the position to determine what checkbox to check
            //this assumes that you have an array of your checkboxes as well. called checkbox
            checkBox[position].setChecked(!checkBox.isChecked());
        }
    });

ListView是您的列表适配器 List adapter reference
