我的code是:
EditText edt
edt.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
final String number = edt.getText().toString();
int count = arg0.length();
edt.setSelection(count);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
final String number = edt.getText().toString();
}

请尝试以下code
int start =editText.getSelectionStart(); //this is to get the the cursor position
String s = "Some string";
editText.getText().insert(start, s); //this will get the text and insert the String s into the current position
下面是code到删除的EditText选中的文本
Here is the code to delete selected text from EditText
int start = t1.getSelectionStart(); //getting cursor starting position
int end = t1.getSelectionEnd(); //getting cursor ending position
String selectedStr = t1.getText().toString().substring(start, end); //getting the selected Text
t1.setText(t1.getText().toString().replace(selectedStr, "")); //replacing the selected text with empty String and setting it to EditText
