在
android中编辑文本不允许在setError之后更改drawable.
我在密码字段中使用了drawable right,但如果密码字段中出现错误,则不允许在其后更改drawable.错误之前它工作正常.

<EditText
android:id="@+id/edt_reg_password"
style="@style/editText_full_view"
android:layout_height="wrap_content"
android:layout_below="@id/edt_reg_email"
android:layout_marginTop="@dimen/padding_normal"
android:drawableLeft="@mipmap/ic_action_password"
android:drawableRight="@mipmap/ic_action_password_visibility"
android:drawablePadding="@dimen/padding_normal"
android:hint="@string/hint_password"
android:inputType="textPassword"
android:maxLength="25"
android:paddingLeft="@dimen/padding_normal"
tools:visibility="visible" />
用于更改眼睛图标运行时的Java代码
private void setPasswordDrawable()
{
final Drawable showpass_icon = getResources().getDrawable(R.mipmap.ic_action_password_visibility);
final Drawable hidepass_icon = getResources().getDrawable(R.mipmap.ic_action_password_visibility_off);
final Drawable pass_drawable = getResources().getDrawable(R.mipmap.ic_action_password);
pass_drawable.setBounds(0,pass_drawable.getIntrinsicWidth(),pass_drawable.getIntrinsicHeight());
//edtPassword.setCompoundDrawables(pass_drawable,null,showpass_icon,null);
edtPassword.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v,MotionEvent event) {
if (edtPassword.getCompoundDrawables()[2] == null) {
return false;
}
if (event.getAction() != MotionEvent.ACTION_UP) {
return false;
}
if (event.getX() > edtPassword.getWidth() - edtPassword.getPaddingRight()
- showpass_icon.getIntrinsicWidth()) {
if (isPasswordVisible) {
runOnUiThread(new Runnable() {
@Override
public void run() {
//edtPassword.setError(null);
edtPassword.setTransformationMethod(
PasswordTransformationMethod.getInstance());
edtPassword.setSelection(edtPassword.getText().length());
showpass_icon.setBounds(0,showpass_icon.getIntrinsicWidth(),showpass_icon.getIntrinsicHeight());
edtPassword.setCompoundDrawables(pass_drawable,null);
}
});
isPasswordVisible = false;
} else {
runOnUiThread(new Runnable() {
@Override
public void run() {
//edtPassword.setError(null);
edtPassword.setTransformationMethod(
HideReturnsTransformationMethod.getInstance());
edtPassword.setSelection(edtPassword.getText().length());
hidepass_icon.setBounds(0,hidepass_icon.getIntrinsicWidth(),hidepass_icon.getIntrinsicHeight());
edtPassword.setCompoundDrawables(pass_drawable,hidepass_icon,null);
}
});
isPasswordVisible = true;
}
}
return false;
}
});
}
用于设置错误
public void setViewError(View view,String message)
{
if (view instanceof EditText) {
((EditText) view).setError(message);
}
}
解决方法
你可以用这个 –
if(error=true){
editText.setCompoundDrawablesWithIntrinsicBounds(
0,R.drawable.ic_error,0);
editText.setCompoundDrawablePadding(5);}
else{
editText.setCompoundDrawablesWithIntrinsicBounds(
0,R.drawable.ic_corrct,0);
editText.setCompoundDrawablePadding(5);}
