Question

我有一个项目，显示使用地方搜索的献血者列表，我想在每个用户的列表视图中插入一个呼叫按钮，我不知道如何添加它，你能帮我解决这个问题吗？屏幕截图1：屏幕截图2：献血者的每个细节，如姓名，血型和电话都存储在服务器的每个字段中。＆＃34; bld_phn＆＃34;是显示电话号码的文本视图的ID。＆＃34;电话＆＃34;是数组字符串

Answer 1

对于listview中的通话按钮，您可以在列表视图的行文件中添加呼叫按钮图标，如下所示： -

    <Button
        android:id="@+id/buttonCall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Call" />

然后在活动中，您可以在Android中点击呼叫按钮以调用功能来编写下面的代码： -

Intent callIntent = new Intent(Intent.ACTION_CALL); callIntent.setData(Uri.parse("phone number")); startActivity(callIntent);
上面代码中的
电话号码是一个字符串var，您可以在其中添加要呼叫的号码。

我希望它会对你有所帮助。
