我正在尝试使用对话框中的共享首选项保存数据,然后在列表视图中显示该数据。我能够在列表视图中显示数据,但无法使用共享首选项保存数据
这是代码
@Override
protected void onCreate(Bundle savedInstanceState) {
ListView tempListView;
super.onCreate(savedInstanceState);
setContentView(R.layout.templates);
final Dialog dialog=new Dialog(Template.this);
dialog.setContentView(R.layout.temp_dialog);
dialog.setTitle("New Template");
Button btn_ok=(Button)dialog.findViewById(R.id.bt_temp_diolg_ok);
btn_ok.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String edit1=(String) ((EditText)dialog.findViewById(R.id.et_diolg_temp)).getText().toString();
template.add(edit1);
SharedPreferences spf = getSharedPreferences("temp", MODE_MULTI_PROCESS);
SharedPreferences.Editor spfe = spf.edit();
Map alldata=spf.getAll();
spfe.putString("Template", edit1);
spfe.commit();
dialog.dismiss();
temp.notifyDataSetChanged();
tempListView=(ListView)findViewById(R.id.listView_templates);
temp = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,template);
tempListView.setAdapter(temp);
Button btn=(Button)findViewById(R.id.btn_newtemp);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.show();
}
}
这是对话框的代码:
final Dialog dialog=new Dialog(Template.this);
dialog.setContentView(R.layout.temp_dialog);
dialog.setTitle("New Template");
Button btn_ok=(Button)dialog.findViewById(R.id.bt_temp_diolg_ok);
btn_ok.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String edit1=(String) ((EditText)dialog.findViewById(R.id.et_diolg_temp)).getText().toString();
template.add(edit1);
SharedPreferences spf = getSharedPreferences("temp", MODE_MULTI_PROCESS);
SharedPreferences.Editor spfe = spf.edit();
Map alldata=spf.getAll();
spfe.putString("template",edit1);
spfe.commit();
dialog.dismiss();
spf.getString("template", edit1);
temp.notifyDataSetChanged();
}
});
tempListView=(ListView)findViewById(R.id.listView_templates);
temp = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,template);
tempListView.setAdapter(temp);
Button btn=(Button)findViewById(R.id.btn_newtemp);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.show();
}
});
}
}
