android - onConfigurationChanged 不去监听

Question

我的应用程序最初是显示商店标签，从服务中加载获取所有商店名称并适合自动完成后，然后向用户显示自动完成 block ，用户可以选择商店。一旦他选择了用户可见的商店登录 block 。

我的问题是用户选择商店并输入用户名和密码，在点击登录按钮之前，将屏幕旋转到另一边，或者当方向将横向更改为纵向或智慧诗时，它只显示自动完成 block ，没有显示登录 block

意思是。当方向改变时，它会重新创建 Activity ，但不会转到 Autocomplete setOnItemClickListener

list 文件我添加了这一行

     <activity android:name="com.pearson.lsmobile.LoginActivity" android:label="@string/title" android:configChanges="orientation|screenSize|keyboardHidden" android:screenOrientation="unspecified"> </activity>

我的代码是:

 public class LoginActivity extends ShopMainDefaultActivity {
@Nullable @InjectView(R.id.login_button) Button loginButton;
@Nullable @InjectView(R.id.username_text) EditText usernameText;
@Nullable @InjectView(R.id.password_text) EditText passwordText;
@Nullable @InjectView(R.id.remember_check) CheckBox rememberCheck;
@Inject ECollegeApplication app; 
@Inject SharedPreferences prefs;
@Nullable @InjectView(R.id.txtShopFilter) AutoCompleteTextView txtShopFilter;  //Inject
@Nullable @InjectView(R.id.filter_box) LinearLayout filter_box;
@Nullable @InjectView(R.id.login_box) LinearLayout loginBox;
private ArrayAdapter<String> adapter;  //AutoComplete array adapter
protected ECollegeClient client;
private Map<String,Shop> mapShop = new HashMap<String,Shop>();

private class DoneOnEditorActionListener implements OnEditorActionListener {
    public boolean onEditorAction(TextView textView, int actionID, KeyEvent event) {
        if (actionID == EditorInfo.IME_ACTION_DONE) {
            InputMethodManager imm = (InputMethodManager)textView.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(textView.getWindowToken(), 0);
            return true;    
        }
        return false;
    }
}

private void loadShops(){
     buildService(new FetchAllUniversities()).execute();
}

public void onServiceCallSuccess(FetchAllUniversities service) {
    mapUniversity = service.getResult();
    loginBox.setVisibility(View.GONE); // Hide login view
    displaySchool();
    overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
}

/*
 * This method load the universities into array adapter
 */
private void displaySchool(){
    filter_box.setVisibility(View.VISIBLE);
    adapter = new ArrayAdapter<String>(LoginActivity.this,android.R.layout.simple_list_item_1,new ArrayList<String>(mapShop.keySet())); //Initialize array adapter
    txtShopFilter.setAdapter(adapter);// set adapter for the auto complete fields
    txtShopFilter.setThreshold(1); // specify the minimum type of characters before drop-down list is shown

}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    client = app.getClient();
    setContentView(R.layout.login);
    filter_box.setVisibility(View.GONE);
    if (!isOnline()) { //
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle(R.string.app_name);
        builder.setMessage(R.string.e_no_network_connection);
        builder.setIcon(android.R.drawable.ic_dialog_alert);
        builder.setCancelable(false);
        builder.setPositiveButton(android.R.string.ok,
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
        builder.create().show();
        return;
    }else{
        loadShops();
    }

    usernameText.setOnEditorActionListener(new DoneOnEditorActionListener());
    passwordText.setOnEditorActionListener(new DoneOnEditorActionListener());
    rememberCheck.setTextColor(getResources().getColor(R.color.color_primary));

    txtShopFilter.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            loginBox.setVisibility(View.VISIBLE);
            txtShopFilter.setEnabled(false);

        }
    });
}

请帮帮我

有什么解决办法吗？

Answer 1

在方向改变时正在重新创建 Activity

所以你需要在 Activity 被销毁之前保存数据并在重新创建后检索

在这里，您可以在 onSaveInstanceState 中保存自动完成选择的状态，并在 onCreate 或 onRestoreInstanceState 中检索数据
