一、打勾显示输入的密码
private EditText et;
private CheckBox cb;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.password);
et = (EditText)findViewById(R.id.editText1);
cb = (CheckBox)findViewById(R.id.checkBox1);
cb.setOnCheckedChangeListener(new OnCheckedChangeListener(){
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if(cb.isChecked()){
et.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
}
else{
et.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
}
});
}
实时监视EditText内输入的字符
mEditText1.addTextChangedListener(new TextWatcher(){
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
});
