在 android 中从 textwatcher 获取 edittext.settext 数据
getting edittext.settext data from textwatcher in android
我正在 EditText
中设置文本,但是当从 TextWatcher
中获取文本时,它给出的是空字符串。
请检查此代码
for (int i = 0; i < 4; i++) {
et = new EditText(this);
et.setText("hai");
final EditText finalEt = et;
ans.addView(et);
final int finalI = i;
finalEt.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
Log.d("text is",""+finalEt.getText().toString());
}
public void beforeTextChanged(CharSequence s, int start,int count, int after) {}
public void onTextChanged(CharSequence s, int start,int before, int count) {}
}
你会在 onTextChanged
和 afterTextChanged
上得到它,就像这样。
for (int i = 0; i < 4; i++) {
et = new EditText(this);
et.setText("hai");
final EditText finalEt = et;
ans.addView(et);
final int finalI = i;
finalEt.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
String str = s.toString();
Log.d("text is",""+s);
}
public void beforeTextChanged(CharSequence s, int start,int count, int after) {}
public void onTextChanged(CharSequence s, int start,int before, int count) {
Log.d("text is",""+s.toString());
}
}
用这个替换日志
Log.d("text is","" + new String(s.toString()));
