我正在尝试在具有带滚动条的TextView的滚动视图内使用RelativeLayout创建一个android应用,但是每次我尝试滚动TextView时,RelativeLayout都会滚动。
我也尝试了以下解决方案,但无济于事:

how to make a relative layout scrollable when it has many children views?
*我的布局看上去几乎与第3个链接相似,但具有更多控件。
以下是我的布局代码
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"

android:scrollbars = "vertical">

</RelativeLayout>
</ScrollView>
问题:无法滚动Textview(android:id =“ @ + id / testLogs”)
以某种方式,如果我的控件较少(只要未激活布局的可滚动性),则TextView的滚动将起作用。
以下是设备规格。我用来测试的东西:
我不知道为什么TextView滚动si无法正常工作? 请帮忙!

尝试
在XML文件中
android:maxLines = "AN_INTEGER"
android:scrollbars = "vertical"
和Java
tv_desc.setMovementMethod(new ScrollingMovementMethod());
scrollview.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
tv_desc.getParent().requestDisallowInterceptTouchEvent(false);
return false;
}
});
tv_desc.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
tv_desc.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});

请不要介意编码结构...谢谢。

textView.setMovementMethod( new ScrollingMovementMethod( ) );
textView1.setMovementMethod( new ScrollingMovementMethod( ) );
textView2.setMovementMethod( new ScrollingMovementMethod( ) );
