下面是标准键盘上显示的各种输入类型。

以编程方式设置输入类型

editText.setInputType(InputType.TYPE_CLASS_TEXT);

除了TYPE_CLASS_TEXT之外的其他选项可以在文档中找到。

在XML中设置输入类型

<EditText
    android:inputType="text"
/>

文本之外的其他选项可以在文档中找到。

附加的代码

获取当前的InputType

要以编程方式设置EditText的输入类型，必须指定输入类类型为文本。

editPass.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

editText.setInputType(EditorInfo.TYPE_CLASS_NUMBER);

//你可以改变TYPE_…根据您的要求。

根据TextView文档，android:password的编程版本是setTransformationMethod()，而不是setInputType()。比如:

mEdit.setTransformationMethod(PasswordTransformationMethod.getInstance());

应该能行。

芬兰湾的科特林:

    val password = EditText(this)
    password.inputType = InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD
    password.hint = "Password"

隐藏:

edtPassword.setInputType(InputType.TYPE_CLASS_TEXT);
edtPassword.setTransformationMethod(null);

显示:

edtPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);                    
edtPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());
