它是一个游戏,在结束时活动显示分数但在此之前,输入警告框显示在用户需要添加其名称的位置,该名称和分数应该转到数据库。分数正在存储但不是名称。如何从输入警告对话框中获取名称并将其设置在db.insertScore(Score,Name)上。即使将Name声明为全局,它仍然无效 这是我的代码
Bundle extra = getIntent().getExtras();
if (extra != null)
{
showInputDialog();
final int Score = extra.getInt("SCORE");
final int totalQuestion = extra.getInt("TOTAL");
int correctAnswer = extra.getInt("CORRECT");
txtTotalScore.setText(String.format("SCORE : %d", Score));
txtTotalQuestion.setText(String.format("PASSED : %d/%d", correctAnswer, totalQuestion));
progressBarResult.setMax(totalQuestion);
progressBarResult.setProgress(correctAnswer);
//save score
db.insertScore(Score,Name);
}
}
protected void showInputDialog() {
// get prompts.xml view
LayoutInflater layoutInflater = LayoutInflater.from(Done.this);
View promptView = layoutInflater.inflate(R.layout.dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Done.this);
alertDialogBuilder.setView(promptView);
final EditText editText = (EditText) promptView.findViewById(R.id.edittext);
// setup a dialog window
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String Name = editText.getText().toString();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}

未添加它的原因是因为您在对话框中定义了Name
变量,这会将变量的范围限制为该条件。如果我是你,我会创建一个名为name
的类变量,然后为变量创建一个getter和setter。然后在对话框中,您可以调用setName(name)
。然后,当您将数据存储在数据库中时,可以调用db.insertScore(Score,getName());
。另外,FWIW,变量应该是小写的。大写通常保留给类名。

再创建一个函数,将分数和编辑后的名称存储到数据库中。请遵循以下代码。
Bundle extra = getIntent().getExtras();
if (extra != null)
{
final int Score = extra.getInt("SCORE");
final int totalQuestion = extra.getInt("TOTAL");
int correctAnswer = extra.getInt("CORRECT");
txtTotalScore.setText(String.format("SCORE : %d", Score));
txtTotalQuestion.setText(String.format("PASSED : %d/%d", correctAnswer, totalQuestion));
progressBarResult.setMax(totalQuestion);
progressBarResult.setProgress(correctAnswer);
//show dialog
showInputDialog(Score);
}
protected void showInputDialog(final int score) {
// get prompts.xml view
LayoutInflater layoutInflater = LayoutInflater.from(Done.this);
View promptView = layoutInflater.inflate(R.layout.dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Done.this);
alertDialogBuilder.setView(promptView);
final EditText editText = (EditText) promptView.findViewById(R.id.edittext);
// setup a dialog window
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String Name = editText.getText().toString();
storeData(Name, score);
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}
protected void storeData(String name, final int score){
db.insertScore(score,name);
}
