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>

结果:

TextInputLayout的更新代码:

   <androidx.cardview.widget.CardView

    android:layout_height="wrap_content"
    app:layout_constraintBottom_toTopOf="@+id/lg_forget_password"

        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>

结果:

试试这个:

passwordEditText.setInputType(1);

Or

passwordEditText.setInputType(InputType.TYPE_CLASS_TEXT);

如果你想要一个简单的解决方案，你可以使用这个扩展的Android的EditText去这个链接了解更多信息:https://github.com/scottyab/showhidepasswordedittext

将此添加到build.gradle中: 实现“com.github.scottyab: showhidepasswordedittext: 0.8”

然后更改XML文件中的EditText。

来自:< EditText

: < com.scottyab.showhidepasswordedittext.ShowHidePasswordEditText

这是所有。

注意:在XML设计中无法看到它，请尝试在模拟器或物理设备中运行它。

使用复选框并相应地更改输入类型。

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    int start,end;
    Log.i("inside checkbox chnge",""+isChecked);
    if(!isChecked){
        start=passWordEditText.getSelectionStart();
        end=passWordEditText.getSelectionEnd();
        passWordEditText.setTransformationMethod(new PasswordTransformationMethod());;
        passWordEditText.setSelection(start,end);
    }else{
        start=passWordEditText.getSelectionStart();
        end=passWordEditText.getSelectionEnd();
        passWordEditText.setTransformationMethod(null);
        passWordEditText.setSelection(start,end);
    }
}

要显示圆点而不是密码，请设置PasswordTransformationMethod:

yourEditText.setTransformationMethod(new PasswordTransformationMethod());

当然，您可以在XML布局中的edittext元素中默认设置此选项

android:password

要重新显示可读密码，只需传递null作为转换方法:

yourEditText.setTransformationMethod(null);
