Android的刷卡片段上点击 [英] Android Swipe Fragment on click
问题描述
我有一个片段寻呼机,我建的第一个片段的按钮。
现在,我想让它滑动到第二个片段,当我点击该按钮。
我建立了这个至今:
公共类方法文档扩展片段{ @TargetApi(Build.VERSION_ codeS.JELLY_BEAN)
@覆盖
公共查看onCreateView(最终LayoutInflater吹气,最后的ViewGroup容器,
捆绑savedInstanceState){ 查看机器人= inflater.inflate(R.layout.how_to,集装箱,FALSE);
((的TextView)android.findViewById(R.id.howTo))的setText(HOWTO); 按钮next_frag =(按钮)android.findViewById(R.id.next_frag);
next_frag.setOnClickListener(新View.OnClickListener(){
@TargetApi(Build.VERSION_ codeS.JELLY_BEAN)
公共无效的onClick(视图v){
//滑动即可page`?
查看机器人= inflater.inflate(R.layout.how_to,集装箱,FALSE); }
});
返回机器人; }
}
它没有工作。有谁知道如何解决这个问题。
编辑:
activity_main.xml中
<?XML版本=1.0编码=UTF-8&GT?;
< android.support.v4.view.ViewPager
的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:ID =@ + ID /寻呼机
机器人:文字样式=大胆
机器人:layout_width =match_parent
机器人:layout_height =match_parent/>
和我的按钮,将改变片段XML:
<?XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =FILL_PARENT
机器人:layout_height =FILL_PARENT
机器人:方向=垂直
机器人:背景=@绘制/ how_to_gradient>
<按钮
机器人:ID =@ + ID / next_frag
机器人:layout_width =match_parent
机器人:layout_height =WRAP_CONTENT
机器人:文字颜色=#FFF
机器人:比重=中心
机器人:layout_weight =1
机器人:shadowDx =0
机器人:shadowDy =0
机器人:shadowRadius =5
机器人:TEXTSIZE =21sp
机器人:文字样式=大胆
机器人:文字=测试
机器人:背景=@绘制/ border_inner_orange/>< / LinearLayout中>
尝试在按钮点击使用此:
viewPager.setCurrentItem(nextposition);
或者如果你想有一个平滑滚动,你可以使用
viewPager.setCurrentItem(位置,真正的);
编辑:
您可以通过获取视图寻呼机的当前页:
viewPager.getCurrentItem();
获得数量和放大器;添加+1把值nextposition
编辑:
MainActivity:
里面MainActivity初始化MainActivity的静态实例:
公共静态MainActivity mInstance = NULL;
然后MainActivity的onCreate方法里面这样做:
mInstance =这一点;
以上这些是两个加法您MainActivity ..
您现在的片段公共类方法文档扩展片段{ @TargetApi(Build.VERSION_ codeS.JELLY_BEAN)
@覆盖
公共查看onCreateView(最终LayoutInflater吹气,最后的ViewGroup容器,
捆绑savedInstanceState){ 查看机器人= inflater.inflate(R.layout.how_to,集装箱,FALSE);
((的TextView)android.findViewById(R.id.howTo))的setText(HOWTO);ViewPager viewPager =(ViewPager)MainActivity.mInstance.findViewById(R.id.pager);INT nextFragment = viewPager.getCurrentItem()+ 1; 按钮next_frag =(按钮)android.findViewById(R.id.next_frag);
next_frag.setOnClickListener(新View.OnClickListener(){
@TargetApi(Build.VERSION_ codeS.JELLY_BEAN)
公共无效的onClick(视图v){
//滑动即可page`?viewPager.setCurrentItem(nextFragment); }
});
返回机器人; }
}
I have a Fragment pager, I built a button on the first fragment. Now I want to make it swipe to the second fragment when I click on that button. I built this so far:
public class HowTo extends Fragment {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
View android = inflater.inflate(R.layout.how_to, container, false);
((TextView) android.findViewById(R.id.howTo)).setText("howto");
Button next_frag = (Button) android.findViewById(R.id.next_frag);
next_frag.setOnClickListener(new View.OnClickListener() {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void onClick(View v) {
// Swipe to page`?
View android = inflater.inflate(R.layout.how_to, container, false);
}
});
return android;
}
}
It did not work. Does anyone know how to solve this issue.
EDIT: activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:textStyle="bold"
android:layout_width="match_parent"
android:layout_height="match_parent" />
And xml with my button that is going to change fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/how_to_gradient">
<Button
android:id="@+id/next_frag"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#fff"
android:gravity="center"
android:layout_weight="1"
android:shadowDx="0"
android:shadowDy="0"
android:shadowRadius="5"
android:textSize="21sp"
android:textStyle="bold"
android:text="test"
android:background="@drawable/border_inner_orange"/>
</LinearLayout>
Try using this on Button Click:
viewPager.setCurrentItem(nextposition);
or if you want a smooth scroll you can use
viewPager.setCurrentItem(position,true);
Edit:
You can get the Current page of View pager by :
viewPager.getCurrentItem();
get the number & add +1 to put the value in nextposition
EDITED:
MainActivity:
inside MainActivity initialize a static instance of MainActivity:
public static MainActivity mInstance = null;
then inside onCreate method of MainActivity do like this:
mInstance = this;
these above are two additions in your MainActivity..
Now Your Fragment
public class HowTo extends Fragment {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
View android = inflater.inflate(R.layout.how_to, container, false);
((TextView) android.findViewById(R.id.howTo)).setText("howto");
ViewPager viewPager = (ViewPager) MainActivity.mInstance.findViewById(R.id.pager);
int nextFragment = viewPager.getCurrentItem() + 1;
Button next_frag = (Button) android.findViewById(R.id.next_frag);
next_frag.setOnClickListener(new View.OnClickListener() {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void onClick(View v) {
// Swipe to page`?
viewPager.setCurrentItem(nextFragment);
}
});
return android;
}
}
