有没有一个聪明的方法让用户在隐藏和查看密码之间切换在一个android EditText? 许多基于PC的应用程序都允许用户这样做。

TextInputLayout的更新代码:
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toTopOf="@+id/lg_forget_password"
app:layout_constraintTop_toBottomOf="@+id/lg_name"
app:cardElevation="@dimen/dp20"
android:layout_marginStart="@dimen/dp20"
app:cardCornerRadius="@dimen/dp10"
android:layout_marginEnd="@dimen/dp20"
android:id="@+id/textField">
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:backgroundTint="@android:color/transparent"
app:boxStrokeWidth="0dp"
app:boxStrokeWidthFocused="0dp"
app:endIconMode="password_toggle"
app:hintEnabled="false"

<com.google.android.material.textfield.TextInputEditText
android:id="@+id/lg_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/input_bg"
android:drawableStart="@drawable/ic_baseline_lock_24"
android:drawablePadding="@dimen/dp10"
android:fontFamily="@font/roboto_flex"
android:hint="@string/password"
android:inputType="textPassword"
android:padding="@dimen/dp15"
android:singleLine="true" />
</com.google.android.material.textfield.TextInputLayout>
</androidx.cardview.widget.CardView>

你可以使用app:passwordToggleEnabled="true"
下面是一个例子
<android.support.design.widget.TextInputLayout
android:id="@+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:textColorHint="@color/colorhint"
android:textColor="@color/colortext">

在XML中这样做

android:layout_width="fill_parent"
android:orientation="vertical"

<RelativeLayout
android:id="@+id/REFReLayTellFriend"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"

<EditText
android:id="@+id/etpass1"

android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:bottomLeftRadius="10dp"
android:bottomRightRadius="50dp"

android:textColor="#000000"
android:textColorHint="#d3d3d3"
android:textSize="14sp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
<ImageButton
android:id="@+id/imgshowhide1"
android:layout_width="40dp"
android:layout_height="20dp"
android:layout_marginTop="20dp"
android:layout_marginRight="10dp"
android:background="@drawable/showpass"
android:layout_alignRight="@+id/etpass1"/>
</RelativeLayout>
boolean show=true;
//on image click inside password do this
if(show){
imgshowhide2.setBackgroundResource(0);
imgshowhide2.setBackgroundResource(R.drawable.hide);
etpass2.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
etpass2.setSelection(etpass2.getText().length());
show=false;
}else{
imgshowhide2.setBackgroundResource(0);
imgshowhide2.setBackgroundResource(R.drawable.showpass);
