如何制作“不再问我”对话框弹出框？人造人

编辑：当心！代码重复。由于我不再为Android开发，因此我无法重构下面的代码。

它在Android首选项中设置一个值，并检查它是否将显示对话框。

复选框.xml资源/布局中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout_root"
    android:layout_width="fill_parent"

活动.java

public class MyActivity extends Activity {
    public static final String PREFS_NAME = "MyPrefsFile1";
    public CheckBox dontShowAgain;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    protected void onResume() {
        AlertDialog.Builder adb = new AlertDialog.Builder(this);
        LayoutInflater adbInflater = LayoutInflater.from(this);
        View eulaLayout = adbInflater.inflate(R.layout.checkbox, null);
        SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
        String skipMessage = settings.getString("skipMessage", "NOT checked");

        dontShowAgain = (CheckBox) eulaLayout.findViewById(R.id.skip);
        adb.setView(eulaLayout);
        adb.setTitle("Attention");
        adb.setMessage(Html.fromHtml("Zukky, how can I see this then?"));

        adb.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                String checkBoxResult = "NOT checked";

                if (dontShowAgain.isChecked()) {
                    checkBoxResult = "checked";
                }

                SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
                SharedPreferences.Editor editor = settings.edit();

                editor.putString("skipMessage", checkBoxResult);
                editor.commit();

                // Do what you want to do on "OK" action

                return;
            }
        });

        adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                String checkBoxResult = "NOT checked";

                if (dontShowAgain.isChecked()) {

                editor.putString("skipMessage", checkBoxResult);                    
                editor.commit();

                // Do what you want to do on "CANCEL" action

                return;
            }
        });

        if (!skipMessage.equals("checked")) {
            adb.show();
        }

        super.onResume();
    }
}

您必须创建一个自定义对话框，例如，在其上设置自定义内容视图（使用 setView（））。该自定义布局可以是（用于显示信息）+ a（带 ）。在对话框按钮的集合中，您可以获得该按钮的状态，如果用户检查了它，那么您在首选项中设置了一个标志（例如，布尔值为true）。AlertDialogTextViewCheckBoxDo not ask me againOnClickListenerCheckBox

下次用户使用该应用程序时，您将从首选项中检查该布尔值，如果将其设置为true，则不会显示对话框，否则用户未选中该对话框，因此您再次向他显示对话框。CheckBox
