android - 首次启动时GONE，点击按钮后可见，并保存当前状态以恢复

Question

我这里有问题。

Activity A--->B--->C A是欢迎页面，B是用户添加页面，C是用户详情输入页面

我在我的活动 B 中设置了 10 行。我想在第一次启动此应用程序时使其最初处于 GONE 模式，并且在我单击“添加”后，每次单击都会显示该行。如果我单击行中的下一个按钮，我将被定向到活动 C。或者如果我在活动 B 中按回，我将被定向到 A。

现在，我的问题是，我想在第一次启动此应用程序时将其设置为 GONE 模式，然后单击“添加”后，每次单击都会显示该行。而且，如果我去 C 并返回 B，或者返回 A 并返回 B，我希望我显示 VISIBLE 或 GONE 的行保持以前的状态。我怎样才能做到这一点？

您想要使用 aListView并动态添加和删除行，并且您想要使用数组而不是变量 1 到 10。例如，此示例演示了如何通过单击 a 中的项目来启动新活动ListView：

    ListView lv = (ListView)findViewById(R.id.listView); // You need to add this!

    // listening to single list item on click
    lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {

          Intent intent = new Intent(AccountSetup.this, AccountSettingActivity.class);
          intent.putExtra("rowNumber", position);
          startActivityForResult(intent, position * 100);
      }
    });

但是，如果不完全重写您的代码，我很难为您提供更详细的帮助。

您可以使用 tprefernce 值来保存每一行的状态。因此，当您退出活动时保存行的值（活动或非活动），以及当您启动活动时，将值加载到活动或非活动行。

这是一个例子：

public static void updateBooleanValue(boolean value, int id, Context context)
{
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    Editor edit = preferences.edit();
    edit.putBoolean(context.getResources().getString(id), value);
    edit.commit();
}

public static boolean getBoolPreference(int id, Context context)
{
    // Initialize preferences
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    return preferences.getBoolean(context.getResources().getString(id), false);

}

函数 updateBooleanValue 设置当前行的状态（真或假）
函数 getBoolPreference 获取当前行的状态（真或假）
id 是您在 string.xml 中设置的例如 R.String.id

就这样。

祝你好运。

android - 首次启动时GONE，点击按钮后可见，并保存当前状态以恢复
