introduction
In project development, you will definitely encounter such needs. It is too troublesome to clean up the data entered into EditText one by one. You need a button to directly delete the data in the entire EditText control at one time. Then I will encapsulate a method for you and call it directly if you have such needs. Without further ado, just upload the code:
/**
*Clear the edit box button
* @param editText EditText control that needs to be cleared
* @param delImageView Clear data picture
*/
protected void clearEditText(final EditText editText, final ImageView delImageView) {
/Listening for text box editing/
(new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// 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 afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
if(().length()!=0){
();
} else {
();
}
}
});
/**Focus change monitoring**/
(new () {
@Override
public void onFocusChange(View arg0, boolean arg1) {
// TODO Auto-generated method stub
if(().length()!=0){
//Delete icon display ();
} else {
//Delete icon to hide ();
}
if(arg1){
//Get focus } else {
//Lost focus, delete icon hide ();
}
}
});
//Delete the icon click and listen event (new () {
@Override
public void onClick(View arg0) {
// Execute clear EditText data ("");
}
});
}
End, just call it where needed according to the needs.
