我正在尝试在一个可用的片段中获取EditText.getText()。toString(),我已经阅读了有关此问题的所有其他问题,但找不到解决方案:我有EditText.getText()。toString( )在放大视图后,在确认按钮的onClick方法中,我检查了按钮的ID是否正确,但未找到错误。 在logcat中,我可以看到在有问题的行之后正确调用了方法saveWord-只有应该用editText填充的String始终为空。如果将硬编码的字符串放在变量上,它将按预期工作。
如果有人可以帮助,将非常高兴!可能只是我忽略的一个愚蠢的错误?
这是我的代码:
public class BingoAddNewFragment extends Fragment {
private static final String LOG_TAG = BingoDataManager.class.getSimpleName();
View v;
public static final String DEFAULT_EDIT_FRAGMENT_TAG = "editFragmentTag";
private Button mConfirmButton;
EditText mAddWords;
String newWord;
String bWord1 = "";
String bWord2 = "";
String bWord3 = "";
String bWord4= "";
String bWord5= "";
String bWord6= "";
String bWord7= "";
String bWord8= "";
String bWord9= "";
String bWord10= "";
String bWord11= "";
String bWord12= "";
String bWord13= "";
String bWord14= "";
String bWord15= "";
String bWord16= "";
String[] bWord = {bWord1, bWord2, bWord3, bWord4, bWord5, bWord6, bWord7, bWord8, bWord9,
bWord10, bWord11, bWord12, bWord13, bWord14, bWord15, bWord16};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
v = inflater.inflate(R.layout.add_bingo_fragment, container, false);
//some other stuff
mConfirmButton = v.findViewById(R.id.button_confirm);
mAddWords = v.findViewById(R.id.editText_addWords);
mConfirmButton.setOnClickListener (new View.OnClickListener() {
@Override
public void onClick(View v) {
//The next line is not working (everything else seems fine) ->
newWord = mAddWords.getText().toString();
Log.d(LOG_TAG, "Begriff: " + newWord + " wird übergeben");
saveWord (newWord);
}
});
mSaveButton = v.findViewById(R.id.button_save_bingo);
mSaveButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
saveBingo();
}
});
public String[] saveWord (String newWord) {
Log.d(LOG_TAG, "Wort: " + newWord + " entgegengenommen.");
for (int i=0; i<16; i++) {
Log.d(LOG_TAG, "i steht bei: " +i);
if (bWord[i].equals("")) {
bWord[i] = newWord;
Log.d(LOG_TAG, "Word als " + (i+1) + ". Begriff gespeichert.");
break;
}
}
return bWord;
}
这是我的布局文件的一部分:

<android.support.constraint.ConstraintLayout

答案 0 :(得分:0)
我找到了解决方案-尽管我仍然不确定为什么它不起作用。 我将按钮更改为ImageButtons,然后突然工作正常。
