我正在尝试从不同片段的 editTexts 获取一些文本.所以我首先要做的是定义我的 mPager 和 mPagerAdapter:
I am trying to get some text from editTexts on different fragments. So what I do first is define my mPager and mPagerAdapter:
a_Atenuacion 活动
public class a_Atenuacion extends FragmentActivity{
private static final int NUM_PAGES = 3;
/**
* The pager widget, which handles animation and allows swiping horizontally to access previous
* and next wizard steps.
*/
private ViewPager mPager;
/**
* The pager adapter, which provides the pages to the view pager widget.
*/
private PagerAdapter mPagerAdapter;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.a_dat_viewpager);
// Instantiate a ViewPager and a PagerAdapter.
mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
}
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch(position){
case 0:
return new a_Dat_Inicio1();
case 1:
return new a_Dat_Inicio2();
case 2:
return new a_Dat_Inicio3();
}
return null;
}
@Override
public int getCount() {
return NUM_PAGES;
}
}
}
然后我得到了我的 3 个片段类(第一个和第二个布局都有一个 editText，但第三个有一个 editText 和一个 button).按钮功能是当我在最后一个片段(fragment3)中时，它采用信息形式(不同的editTexts)并发送到另一个活动.
Then I get my 3 fragments classes (Both 1st and 2nd layouts have an editText, but the 3rd one has an editText and a button). The button function is that when I am in the last fragment (fragment3) it take info form (different editTexts) and send to another activity.
a_Dat_Inicio1 片段
public class a_Dat_Inicio1 extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e("Test", "hello");
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.a_dat_inicio1, container, false);
return view;
}
}
a_Dat_Inicio3 片段
public class a_Dat_Inicio3 extends Fragment {
EditText edit3;
EditText edit2;
EditText edit1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e("Test", "hello");
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.a_dat_inicio3, container, false);
edit1 = (EditText)getActivity().findViewById(R.id.editText1);
final String edit11 = edit1.getText().toString();
edit2 = (EditText)getActivity().findViewById(R.id.editText2);
final String edit22 = edit2.getText().toString();
edit3 = (EditText)view.findViewById(R.id.editText3);
final String edit33 = edit3.getText().toString();
Button but=(Button) view.findViewById(R.id.button);
but.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
//Creamos el bundle
Bundle bundle = new Bundle();
//Le ponemos la variable parametro con el contenido (key, valor)
bundle.putString("edit3", edit33);
bundle.putString("edit2", edit22);
bundle.putString("edit1", edit11);
Intent net= new Intent(v.getContext(),Prueba1.class);
net.putExtras(bundle);
startActivity(net);
}
});
return view;
}
}
最后我在另一个活动(Prueba1.class)上得到了捆绑，奇怪的是我只得到 editText1 的结果(在第一个片段上)，其余的都是空的.
Finally I get bundle on another activity (Prueba1.class) and it is curious that I only get result for editText1 (on 1st fragment) and rest are null.
谁能帮帮我?
提前致谢.
最后我克服了一个接口，这是我认为在已经定义的片段上获得一些东西的唯一方法.
finally I get over an interface, that is the only way I think to get soemthing on already defined fragments.
我的代码是这样的:
第一次定义接口
public interface OnEditTextChanged {
public void onEditPressed1(String edit1);
public void onEditPressed2(String edit1);
public void onEditPressed3(String edit1);
然后是片段活动:
public class a_Dat_Inicio1 extends Fragment {
EditText edit;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e("Test", "hello");
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.a_1dat_inicio1, container, false);
init (view);
return view;
}
OnEditTextChanged editListener;
@Override
public void onAttach(Activity activity){
super.onAttach(activity);
try{
editListener=(OnEditTextChanged) getActivity();
}catch(ClassCastException e){
throw new ClassCastException(activity.toString()+"must implemnt onEditPressed");
}
}
private void init(View view) {
edit=(EditText) view.findViewById(R.id.editText1);
//cada vez que se modifique texto llamar
edit.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable s) {
final String edit11 = edit.getText().toString();
editListener.onEditPressed1(edit11);
}
});
最后在我们的主要活动上，调用方法:
And finally on our main activity, call the method:
public class a_Atenuacion extends FragmentActivity implements OnEditTextChanged {
String dat1;
String dat2;
String dat3;
private static final int NUM_PAGES = 3;
private PagerAdapter mPagerAdapter;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.a_1dat_viewpager);
// Instantiate a ViewPager and a PagerAdapter.
mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
//HERE DO WHATEVER YOU WANT WITH THE DATA CAUGTH ON THE EDIT 1 METHOD
}
@Override
public void onEditPressed1(String edit1) {
if(mPager.getCurrentItem()==0){
dat1=edit1;
Toast bread = Toast.makeText(getApplicationContext(), "edit1", Toast.LENGTH_LONG);
bread.show();
}
}
