我正在尝试从列表视图中获取字符串值并放入另一个视图中。我已经成功地为我的第一个列表视图做到了这一点,但它似乎不适用于我的第三个。(我设法让它工作,但由于我无法理解的原因它现在停止工作)我正在使用完全相同的方法,并且正在检索我试图检索的信息,因为我在运行问题时已经确认它只是不是改变。
代码
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.statseditor);
dbHelper = new PlayerStatsDatabase(this);
dbHelper.open();
Bundle extras = getIntent().getExtras();
if(extras !=null){
//String value = extras.getString("Name");
}
//Clean all data
// dbHelper.deleteAllStats();
//Add some data
//dbHelper.insertSomeCountries();
//Generate ListView from SQLite Database
//displayListView();
// list = getListView();
PlayerNameText = extras.getString("Name");
btnSave2 = (Button) findViewById(R.id.btnSaveStats);
btnClear = (Button) findViewById(R.id.btnClearStats);
txtGoalsScored = (EditText) findViewById(R.id.txtGoal);
txtMinutesPlayed = (EditText) findViewById(R.id.txtMinPlayed);
txtSubstituteIn = (EditText) findViewById(R.id.txtSubIn);
txtSubstituteOut = (EditText) findViewById(R.id.txtSubOut);
radioSubIn = (RadioButton) findViewById (R.id.rdoSubIn);
radioSubOut = (RadioButton) findViewById (R.id.rdoSubOut);
playerRating = (RatingBar) findViewById (R.id.ratingBar1);
//playerTitle = (TextView) findViewById (R.id.textTitle);
playerName = (TextView) findViewById (R.id.textView1);
playerName.setText(PlayerNameText);
//playerTitle.setText (PlayerNameText);
checkBox = (CheckBox) findViewById (R.id.checkBox1);
if (checkBox.isChecked()){
checkBox.append("Booked");
}
final CharSequence checkText = checkBox.getText();
//final Context context =
btnSave2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
PlayerStatsDatabase db = new PlayerStatsDatabase(getApplicationContext());
db.open();
db.createStats(txtGoalsScored.getText().toString(), txtMinutesPlayed.getText().toString(),txtSubstituteIn.getText().toString(),txtSubstituteOut.getText().toString(), checkText.toString());
db.close();
dipsplayPlayerName();
displayListView();
//Intent intent = new Intent(context, ListItemsActivity.class);
// startActivity(intent);
}
});
}
在我使用此方法的第一个实例中,playerName
实际上更改为PlayerNameText
但是当我再次尝试再次使用它时,它不起作用
private void dipsplayPlayerName() {
setContentView (R.layout.statslist);
Bundle extras = getIntent().getExtras();
PlayerNameText = extras.getString("Name");
playerTitle = (TextView) findViewById (R.id.textTitle);
playerTitle.setText (PlayerNameText);
}
有任何想法吗?没有 LogCat,因为应用程序不会崩溃
