Question

我正在使用约束布局在屏幕的每个角对齐我的textview，但看起来好像不起作用。屏幕右侧尺寸的文本将根据左侧尺寸的文本长度对齐。看看附件图片。右侧的文本未正确对齐。由于某些原因，这里还有一些空间。该如何解决？

Answer 1

如果您要对金额进行右对齐和对齐，则不需要以下两行XML：

            var connstr = db.Database.Connection.ConnectionString;
            SqlConnection connection;
            connection = new SqlConnection(connstr);
            connection.Open();
            SqlDataAdapter adapter = null;
            DataTable tab = new DataTable();

            adapter = new SqlDataAdapter("select Query from [Drag-Drop] where [User_ID] = '" + UserID + "' order by Clock desc", connection);
            adapter.Fill(tab);
            string DQuery = tab.Rows[0][0].ToString();

因此，只需删除它们即可提供以下内容：

    app:layout_constraintHorizontal_bias="0.91"
    app:layout_constraintStart_toEndOf="@+id/category"

如果您需要在<TextView android:id="@+id/income_amount" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="$0.00" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="@color/green" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintTop_toTopOf="@+id/income_icon" />右边添加空白，请添加：

16dp

Answer 2

我已将状态TextView调整为TextView的数量，并从右至状态TextView给出了8 dp的值，以使其与TextView的数量对齐。下面是它的代码。

Answer 4

您的错误是这些-您必须删除这些错误

此行的收入金额

app:layout_constraintStart_toEndOf="@+id/category"

此行的状态

app:layout_constraintStart_toEndOf="@+id/frequency"
