关于对文本输入框 EditText的动态监听
直接贴上源码
//自己写一个 ChangableEditText类继承与实现文本监听
public class ChangableEditText extends AutoCompleteTextView implements TextWatcher{ public ChangableEditText(Context arg0, AttributeSet arg1) { super(arg0, arg1); // TODO Auto-generated constructor stub } @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 text, int start, int before, int after) { Log.v("result", text + ""); } }
//接下来看布局
//布局很简单就是一个EditText的改变
//注意一定要带上包名,否则会出错
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.example.testdialog.ChangableEditText android:id="@+id/editText1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" > <requestFocus /> </com.example.testdialog.ChangableEditText> </LinearLayout>
OK,这样就可以用了
