Android：单击提交按钮后将“等待”字符串数据发送到数据库

Question

根据我的问题，我想将用户填写的所有数据提交到名为"mysuggestion" 的数据库表中。由于“状态”和“评论”都没有用户输入，除"status" 和"comment" 列外，表格中的所有列都填充了用户的输入数据。这两列需要填写“等待”字样。

怎么做？下面是我的代码。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_confirm_suggestion);

    final ActionBar abar = getSupportActionBar();
    View viewActionBar = getLayoutInflater().inflate(R.layout.activity_new_suggestion, null);
    ActionBar.LayoutParams params = new ActionBar.LayoutParams(//Center the textview in the ActionBar !
            ActionBar.LayoutParams.WRAP_CONTENT,
            ActionBar.LayoutParams.MATCH_PARENT,
            Gravity.CENTER);
    TextView tvTitle = viewActionBar.findViewById(R.id.title);
    tvTitle.setText("CONFIRMATION");
    abar.setCustomView(viewActionBar, params);
    abar.setDisplayShowCustomEnabled(true);
    abar.setDisplayShowTitleEnabled(false);
    //abar.setDisplayHomeAsUpEnabled(true);
    abar.setHomeButtonEnabled(true);


    txtName = findViewById(R.id.txtName);
    txtBadgeID = findViewById(R.id.txtBadgeID);
    txtPosition = findViewById(R.id.txtPosition);
    txtDepartment = findViewById(R.id.txtDepartment);
    txtFactory = findViewById(R.id.txtFactory);

    //getting the current user
    User user = SharedPrefManager.getInstance(this).getUser();

    //setting the values to the textviews
    txtName.setText(user.getName());
    txtBadgeID.setText(user.getBadgeid());
    txtPosition.setText(user.getPosition());
    txtDepartment.setText(user.getDepartment());
    txtFactory.setText(user.getFactory());

    etReviewer = findViewById(R.id.etReviewer);

    etPresent = findViewById(R.id.etPresent);
    etDetails = findViewById(R.id.etDetails);
    etBenefit = findViewById(R.id.etBenefit);
    imgAttach = findViewById(R.id.imgAttach);

    SharedPreferences sharedPreferences = getSharedPreferences("MyData", MODE_PRIVATE);
    String reviewer =  sharedPreferences.getString("reviewer",DEFAULT);
    String title = sharedPreferences.getString("title",DEFAULT);

    String photo = sharedPreferences.getString("photo",DEFAULT);
    String status = sharedPreferences.getString("status",DEFAULT);
    String comment = sharedPreferences.getString("comments",DEFAULT);

    etReviewer.setText(reviewer);
    etTitle.setText(title);
    etYear.setText(year);
    etMonth.setText(month);
    etSuggestWill.setText(suggestionwill);
    etPresent.setText(present);
    etDetails.setText(details);
    etBenefit.setText(benefit);
    imgAttach.setImageBitmap(base64ToBitmap(photo));

}

当您从 SharedPreferences 获取 status 和 comment 数据时，将其默认值设置为“waiting”，如下所示 -

String status = sharedPreferences.getString("status","waiting");
String comment = sharedPreferences.getString("comments","waiting");

我希望它对你有用。谢谢
