我已经为An Edittext变量设置了一个标签。我想在文本TextWatcher afterTextChanged方法中获取该标签。但是有一个可编辑的参数而不是Edittext。
这是我的代码.....
EditText filled = new EditText(DamageCount.this);
filled.setId(100);
filled.setTag(5);
我希望在
中获取该标记@Override
public void afterTextChanged(Editable s) {
}
这种方法
------被修改---------------- 我的整个java类
public class DamageCount extends Activity {
private Button button_next;
static TableLayout tl = null;
private DbWorker dbworker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_damage_count);
DamageCount.this

Static_Values.arrayListdam_no = new ArrayList<DamegeItemSerialNoModel>();
button_next.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
/*Intent new_one = new Intent(DamageCount.this,
Invoice_or_prev.class);
startActivity(new_one);
finish();*/
for(DamegeItemSerialNoModel dmmm :Static_Values.arrayListdam_no)
{
System.out.println("Item id is "+dmmm.getItem_id()+" serial no is "+dmmm.getSerial_no());
}
}
});

在Textwatcher类中创建一个构造函数，并将edittext传递给int。
public class MyTextWatcher implements TextWatcher
{
private transient EditText editText = null;
public MyTextWatcher(EditText editText)
{
super();
this.editText = editText;
}
@Override
public void afterTextChanged(Editable arg0)
{
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3)
{
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3)
{
// TODO Auto-generated method stub
}
}

如果您想将Editable转换为简单文字行（String），请在您的方法中使用此功能：
@Override
public void afterTextChanged(Editable s) {
String str = s.toString();
}
