..在其他片段中,这可行。
Fragment fragment = null;
fragment = new Fragment_2();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
但是在onclick事件中
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
public class Fragment1 extends Fragment implements
Button btnuevaventa;
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
btnuevaventa=(Button)getView().findViewById(R.id.bt_nuevaventa);
btnuevaventa.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Fragment fragment = null;
fragment = new Fragment_2();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
});
这是activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>

答案 0 :(得分:2)
你处理这个错误,你想通过托管它们的Activity加载片段,而不是从其他片段加载...所以你使用一个接口告诉Activity执行代码,因为在这种情况下R.id.fragment_container是目前不是Fragment中的id。尝试类似:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
public class Fragment1 extends Fragment
Button btnuevaventa;
ClickCallback mCallback;
public interface ClickCallback{
void buttonClicked();
}
@Override
public void onAttached(Activity activity){
super.onAttach(activity);
mCallback = (ClickCallback) activity;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
btnuevaventa=(Button)getView().findViewById(R.id.bt_nuevaventa);
btnuevaventa.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mCallback.buttonClicked();
}
});
}
}
然后在你的Activity中实现接口:
Activity implements ClickCallback
@Override
public void buttonClicked(){
Fragment fragment = null;
fragment = new Fragment_2();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
