我在一份意见书中展示了一些数据。 关于活动启动(Creod onCreate)问题,我用数据填写了意见书,希望向下游。
我尝试使用getScrollView(ScrollView.FOCUS_DOWN)
。 当我把它当作点击行动时,该方法就发挥了作用。
在活动启动时如何向下层传递雕像? 这意味着,在第一次展示时,这种观点已经发展到底。

需要做如下工作:
getScrollView().post(new Runnable() {
@Override
public void run() {
getScrollView().fullScroll(ScrollView.FOCUS_DOWN);
}
});
这样,这种观点首先得到更新,然后向“新的”底线发展。
添加以下代码:
final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
scrollview.post(new Runnable() {
@Override
public void run() {
scrollview.fullScroll(ScrollView.FOCUS_DOWN);
}
});
对我来说,这项工作是:
scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
scrollview.post(new Runnable() {
public void run() {
scrollview.fullScroll(View.FOCUS_DOWN);
}
});
}
});
在布局档案中,你可以这样做:
android:id="@+id/listViewContent"
android:layout_width="wrap_content"
android:layout_height="381dp"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll">
scrollView.postDelayed(new Runnable() {
@Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
},1000);
引言
final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
scrollview.post(new Runnable() {
@Override
public void run() {
scrollview.fullScroll(ScrollView.FOCUS_DOWN);
}
});
在你对数据作修改后添加这一单一字句:
yourScrollview.fullScroll(ScrollView.FOCUS_DOWN);
这是这样做的最佳方式。
scrollView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
scrollView.post(new Runnable() {
@Override
public void run() {
scrollView.fullScroll(View.FOCUS_DOWN);
}
});
}
});
在初步确定贵组织组成部分并填写数据之后。 在您的创建方法中添加这些内容
Runnable runnable=new Runnable() {
@Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
};
scrollView.post(runnable);
