让我从一张图片开始：

在此处输入图像描述

正如你所看到的，它几乎可以满足我的需要，除了“电影”掉到下一行——这看起来真的很可怕。 这是我的 XML 代码：

        <TextView
            android:id="@+id/myMasterCat_Item"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="left"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="2dp"
            android:layout_weight="99"
            android:text="Item"
            android:textColor="#222"
            android:textSize="18sp" >
        </TextView>

        <TextView
            android:id="@+id/myMastCat_Cat"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="2dp"
            android:layout_weight="1"
            android:gravity="right"
            android:text="MasterCat"
            android:textColor="#999"
            android:textSize="15sp" >
        </TextView>
    </LinearLayout>

我该如何设置它以使其不会以这种方式发生？

你可以试试这个：

<LinearLayout
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:orientation="horizontal"
>
<TextView
            android:id="@+id/myMasterCat_Item"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="2dp"
            android:layout_weight="1"
            android:text="Item"
            android:textColor="#222"
            android:textSize="18sp" >
        </TextView>

        <TextView
            android:id="@+id/myMastCat_Cat"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="2dp"
            android:text="MasterCat"
            android:textColor="#999"
            android:textSize="15sp" >
        </TextView>
</LinearLayout>

另请注意，如果您使用 weight 属性，则应根据要影响的尺寸将 width 或 height 属性设置为 0dp。

这是 CustomView 的另一种解决方案：https ://github.com/merterhk/JustifiedTextView 只需将类添加到您的 src 文件夹即可使用。

import java.util.ArrayList;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;

public class JustifiedTextView extends View {
        String text;
        ArrayList<Line> linesCollection = new ArrayList<Line>();

        float textSize = 42f, lineHeight = 57f, wordSpacing = 15f, lineSpacing = 15f;
        float onBirim, w, h;
        float leftPadding, rightPadding;

        public JustifiedTextView(Context context, String text) {
                super(context);

}

要使用：

JustifiedTextView jtv= new JustifiedTextView(getApplicationContext(), "Lorem ipsum dolor sit amet... ");
LinearLayout place = (LinearLayout) findViewById(R.id.book_profile_content);
place.addView(jtv);
