问题描述
我正在使用SwipeRefreshLayout刷新内容.
问题在于它正在运行，但是向下滑动时看不到.
The problem is that it is working, but is not visible while swiping down.
这是我在xml文件中有SwipeRefreshLayout的方式:
Here's how I have SwipeRefreshLayout in xml file:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.abc.xyz.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipetorefresh"
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<include layout="@layout/content_main"/>
</android.support.v4.widget.SwipeRefreshLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/ic_add_white_24dp"/>
</android.support.design.widget.CoordinatorLayout>
这是content_main.xml文件的代码:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.abc.xyz.MainActivity"
tools:showIn="@layout/app_bar_main">
<TextView
android:id="@+id/main_txt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="xxx"
android:textSize="17sp"/>
<TextView
android:id="@+id/main_txt2"
android:layout_below="@+id/main_txt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="xxx"
android:textStyle="bold"
android:textSize="17sp"/>
<TextView
android:id="@+id/main_txt3"
android:layout_below="@+id/main_txt2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="xxx"
android:textSize="16sp"/>
<TextView
android:id="@+id/main_txt4"
android:layout_below="@+id/main_txt3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="xxx"
android:textStyle="bold"
android:textSize="17sp"/>
<TextView
android:id="@+id/main_txt_swipetorefresh"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="xxx"
android:layout_centerInParent="true"
android:gravity="center_horizontal|center_vertical"/>
<TextView
android:id="@+id/main_txt5"
android:layout_below="@+id/main_txt4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="xxx"
android:textSize="16sp"/>
<TextView
android:id="@+id/main_txt6"
android:layout_below="@+id/main_txt5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="xxx"
android:textStyle="bold"
android:textSize="17sp"/>
<TextView
android:id="@+id/main_txt7"
android:layout_below="@+id/main_txt6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="xxx"
android:textSize="16sp"/>
</RelativeLayout>
这是Java文件中的样子:
Here's how it is in java file:
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipetorefresh);
swipeRefreshLayout.setColorSchemeColors(Color.parseColor("#00BCD4"), Color.parseColor("#FF9800"), Color.parseColor("#339a60"));
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
swipeRefreshLayout.setRefreshing(true);
}
});
请让我知道这是怎么回事?
Please let me know what's going wrong here?
很抱歉，如果问题的格式似乎不正确.我仍然是初学者.
Sorry, if question seems badly formatted. I'm still a beginner.
推荐答案
按照 skywall 的建议，我包装了NestedScrollView中有效！
As suggested by skywall, I wrapped content_main.xml in NestedScrollView and it worked!
这是编辑的content_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.abc.xyz.MainActivity"
tools:showIn="@layout/app_bar_main">
<TextView
android:id="@+id/main_txt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="xxx"
android:textSize="17sp"/>
<TextView
android:id="@+id/main_txt2"
android:layout_below="@+id/main_txt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="xxx"
android:textStyle="bold"
android:textSize="17sp"/>
<TextView

android:layout_height="wrap_content"

android:textSize="16sp"/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
