保存listview 的 item 中的edittext的值 SharedPreferences方法的使用问题 遇到一个麻烦求解决
在adapter里面定义了静态的函数保存edittext然后再listview所在的Fragment的onPause中调用，切换fragment发现并没有读取到保存的数据，求大神帮忙解决，看一下是哪里除了问题啊。。
public class HotSpotsListAdapter extends BaseAdapter {
public static Context context;
List list;
public static EditText edt_input_1, edt_input_2, edt_input_3, edt_input_4;
public static EditText edt_hotspots_name, edt_hotspots_password;
public HotSpotsListAdapter(Context context, List<String> list) {
this.context = context;
this.list = list;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return list.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.network_hotspots_list_item, null);
TextView text_left = (TextView) convertView.findViewById(R.id.hotspots_list_left_text);
RelativeLayout relativeLayout = (RelativeLayout) convertView.findViewById(R.id.hotspots_item_content);
relativeLayout.setBackgroundColor(Color.parseColor("#a7ffffff"));
text_left.setText(list.get(position).toString());
if (HotSpotsFragment.list_selected_position == position) {
relativeLayout.setBackgroundColor(Color.WHITE);
}
TextView textView = (TextView) convertView.findViewById(R.id.hotspots_list_text);
edt_hotspots_name = (EditText) convertView.findViewById(R.id.name_edit);
edt_hotspots_password = (EditText) convertView.findViewById(R.id.password_edit);

SharedPreferences read_name = context.getSharedPreferences("hotspots_user_name", Context.MODE_PRIVATE);

switch (position) {

edt_input_1.setText(ip_input1);
edt_input_2.setText(ip_input2);
edt_input_3.setText(ip_input3);
edt_input_4.setText(ip_input4);

public static void WriteUserEditInfo() {

editor.putString("edt_ip_input1", edt_input_1.getText().toString());
editor.putString("edt_ip_input2", edt_input_2.getText().toString());

editor.commit();
}
public static void WriteUserNameInfo() {
SharedPreferences userdetect = context.getSharedPreferences("hotspots_user_name", 0);
SharedPreferences.Editor editor = userdetect.edit();
/* editor.putString("edt_ip_input1", edt_input_1.getText().toString());
editor.putString("edt_ip_input2", edt_input_2.getText().toString());
editor.putString("edt_ip_input3", edt_input_2.getText().toString());
editor.putString("edt_ip_input4", edt_input_4.getText().toString());*/
editor.putString("edt_name", edt_hotspots_name.getText().toString());
/* editor.putString("edt_password", edt_hotspots_password.getText().toString());*/
editor.commit();
}
public static void WriteUserPasswordInfo() {
SharedPreferences userdetect = context.getSharedPreferences("hotspots_user_password", 0);
SharedPreferences.Editor editor = userdetect.edit();
/* editor.putString("edt_ip_input1", edt_input_1.getText().toString());
editor.putString("edt_ip_input2", edt_input_2.getText().toString());
editor.putString("edt_ip_input3", edt_input_2.getText().toString());
editor.putString("edt_ip_input4", edt_input_4.getText().toString());*/
// editor.putString("edt_name", edt_hotspots_name.getText().toString());
editor.putString("edt_password", edt_hotspots_password.getText().toString());
editor.commit();
}
}
这是adapter里面的代码，然后再fragment中
@Override
public void onPause() {
System.out.println(HotSpotsListAdapter.edt_input_1.getText().toString());
adapter_hotSpotsList.WriteUserEditInfo();
adapter_hotSpotsList.WriteUserNameInfo();
adapter_hotSpotsList.WriteUserPasswordInfo();
super.onPause();
Log.e("HotSpots", "onPause");
}
但是切换fragment执行onPause后数据并没有读取到 应该是没有存进去 想请教一下这里该如何调用？才能正确的存到edittext的值呢？
