大家好，我有一个带按钮的片段。我想在单击按钮时打开fragment2。
最好的解决方案是什么？
您能为此举例吗？
在XML片段1中：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="116dp"
android:background="#0000"
android:drawableTop="@drawable/autobus"
android:onClick="OPENFRAGMENT"
android:text="ooo" />
在fragment1中：
public class Fragment1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View info = inflater.inflate(R.layout.info, container, false);
return info;
}
public void OPENFRAGMENT(View view)
{
}
在fragment2中：
public class Fragment2 extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View frag = inflater.inflate(R.layout.frag2, container, false);
return frag;
}
}
主要活动：
public class MainActivity extends SherlockFragmentActivity {
ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;
public boolean StatusConnection = false;
public int thread = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
Tab = (ViewPager)findViewById(R.id.pager);
Tab.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(
position);
Tab.setCurrentItem(position);
}
});
Tab.setAdapter(TabAdapter);
actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.TabListener tabListener = new ActionBar.TabListener(){
@Override
public void onTabReselected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
@Override
public void onTabSelected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
Tab.setCurrentItem(arg0.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
};
actionBar.addTab(actionBar.newTab().setText("A").setTabListener(tabListener));
actionBar.addTab(actionBar.newTab().setText("B").setTabListener(tabListener));
actionBar.addTab(actionBar.newTab().setText("C").setTabListener(tabListener));
@Override
public Fragment getItem(int i) {
switch (i) {
case 0:
return new Info();
case 1:
return new B();
case 2:
return new C();
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:layout_width="match_parent"
android:layout_height="match_parent" />
先感谢您！
最佳答案
首先，您必须使用以下代码从第一个片段上的按钮获取视图：
btnChFrag = info.findViewById(R.id.button1);
（信息是您的片段布局的视图）
那么您需要在该按钮上设置onclicklistener
btnChFrag.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Fragment2 newFragment = new Fragment2();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.container, newFragment);
ft.commit();
}
在MainActivity视图上使用容器更改R.id.container
所以您在fragment1上的代码将是：
public class Fragment1 extends Fragment {
private Button btnChFrag
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View info = inflater.inflate(R.layout.info, container, false);
btnChFrag = info.findViewById(R.id.button1);
//set button onclicklistener here
return info;
}
- - -编辑 - - -
对不起，我完全忘了你想用按钮来做，我不好
这是fragment1的代码
public class Fragment1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View info = inflater.inflate(R.layout.info, container, false);
Button btn1 = (Button)rootView.findViewById(R.id.button1);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
((MainActivity)Fragment1.this.getActivity()).Tab.setCurrentItem(2);
}
});
return info;
}
尝试了一下，它有效:)
关于android - 将fragment1切换为fragment2，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/23621279/
