我想從不同片段上的editTexts獲取一些文本。所以，我做什麼，首先是定義我mPager和mPagerAdapter：獲取不同片段上的EditText值
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;
}
}
}
然後，我讓我的3個片段班（兩個第一和第二的佈局有一個EditText，但第三人有一個EditText和按鈕）。按鈕功能是，當我在最後一個片段（frament3）時，它將信息形式（不同的editTexts）發送到另一個活動。
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; }}
公共類a_Dat_Inicio3擴展片段{
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;
}
}
最後我得到捆綁在另一個活動（Prueba1.class）和奇怪的是，我只得到了結果editText1（上第一個片段），其餘部分爲空。
有人可以幫我嗎？
在此先感謝。
您可以使用'SharedPreferences' – Si8
在將其放入捆綁包之前，確保其餘的EditText值不爲空。 –
我敢肯定我檢查過了，這沒有錯:( – Txispas
