同时滚动多个 TextView [英] Scroll multiple TextViews simultaneously

问题描述

我有一个来自文件的字符串，该字符串存储到 3 个单独的 TextView 中，因为我在使用单个 TextView 时遇到了对齐问题.如何仅滚动屏幕的这一部分以查看文件的所有内容?

I have a string from a file that am storing into 3 separate TextViews because I was having alignments issues with a single TextView. How can I scroll only this section of my screen to see all of the contents of the file?

BufferedReader buf = new BufferedReader(new FileReader(file));
while((line = buf.readLine())!= null) {

    StringTokenizer st = new StringTokenizer(line);

    a = st.nextToken();
    b = st.nextToken();
    c = st.nextToken();

    text1.append(a + '\n');
    text2.append(b + '\n');
    text3.append(c + '\n');
}

dp1.setText(text1);
dp2.setText(text2);
dp3.setText(text3);

推荐答案

如果需要，您可以使用以下 xml 并进行一些调整，

You can use the following xml with a few tweaks if needed,

<HorizontalScrollView
     android:layout_width="wrap_content"
     android:layout_height="wrap_content">

  <TextView  android:id="@+id/dp1"... />
  <TextView  android:id="@+id/dp2"... />
  <TextView  android:id="@+id/dp3"... /> 
</HorizontalScrollView>

现在在你的java代码中，你可以访问它们，

And now in your java code, you can access them as,

TextView textV1 = (TextView)findViewById(R.id.dp1);
TextView textV2 = (TextView)findViewById(R.id.dp2);
TextView textV3 = (TextView)findViewById(R.id.dp3);

textV1.setText(text1);
textV2.setText(text2);
textV3.setText(text3);

如果你愿意，你可以使用垂直滚动条，

if you want you can use vertical scroll bars as,

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:scrollbars="vertical" 
    android:layout_height="set the height here" >

</ScrollView>
