java - 选中复选框后仅显示一次对话框

Question

我在 oncreate 中有一个带有复选框的对话框。如果选中此复选框，则下次打开应用程序时不会显示对话框。我已将复选框状态保存在共享首选项中，它会显示我是否已选中该复选框，但对话框在启动时仍打开..出了什么问题？

//对话框 查看 checkBoxView = View.inflate(this, R.layout.checkbox, null); CheckBox checkBox = (CheckBox) checkBoxView.findViewById(R.id.checkbox); checkBox.setChecked(getFromSP("checkBox"));

checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

private void saveInSp(String key,boolean value){
    SharedPreferences preferences = getApplicationContext().getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putBoolean(key, value);
    editor.commit();
}
    @Override
    public void onCheckedChanged(CompoundButton buttonView,
            boolean isChecked) {
        // TODO Auto-generated method stub
        switch(buttonView.getId()){
        case R.id.checkbox:
        saveInSp("checkBox",isChecked);

        break;
        }
    }
}); 
checkBox.setText("Never show it");

SharedPreferences preferences = getApplicationContext().getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);

boolean hasBeenChecked = preferences.getBoolean("checkbox", false);

if (!hasBeenChecked) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(" TITLE");
    builder.setMessage(" blablabla ")
           .setView(checkBoxView)
           .setCancelable(false)

           .setNeutralButton("Ok", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
               }
           }).show();

    } 

Answer 1

我愿意:

• (非必要)从匿名 OnCheckedChangeListener 中删除 saveInSp 并将其添加到 Activity 中，例如
• (非必要)您可以通过引用 MyActivity.this.saveInSp 从监听器调用 saveInSp

• 然后，在初始化并显示警报之前...

  SharedPreferences preferences = getApplicationContext().getSharedPreferences("PROJECT_NAME", android.content.Context.MODE_PRIVATE);
  
  boolean hasBeenChecked = preferences.getBoolean("checkBox", false);
  
  if (!hasBeenChecked) {
  
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
      builder.setTitle(" TITLEs");
      builder.setMessage(" blablabla ")
             .setView(checkBoxView)
             .setCancelable(false)
  
             .setNeutralButton("Ok", new DialogInterface.OnClickListener() {
                 public void onClick(DialogInterface dialog, int id) {
                      dialog.cancel();
                 }
             }).show();
  }
