How do we set the input type for an EditText programatically? I'm trying:

我们如何以编程方式设置 EditText 的输入类型?我想:

mEdit.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);

it doesn't seem to have any effect.

它似乎没有任何效果。

According to the TextView docs, the programmatic version of android:password is setTransformationMethod(), not setInputType(). So something like:

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

mEdit.setTransformationMethod(PasswordTransformationMethod.getInstance());

should do the trick.

应该做的伎俩。

For setting the input type for an EditText programmatically, you have to specify that input class type is text.

要以编程方式设置 EditText 的输入类型,您必须指定输入类类型为文本。

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

回答by Brian Reinhold

This may be of help to others like me who wanted to toggle between password and free-text mode. I tried using the input methods suggested but it only worked in one direction. I could go from password to text but then I could not revert. For those trying to handle a toggle (eg a show Password check box) use

这可能对像我这样想要在密码和自由文本模式之间切换的其他人有所帮助。我尝试使用建议的输入法,但它只在一个方向上起作用。我可以从密码到文本,但后来我无法恢复。对于那些试图处理切换(例如显示密码复选框)的人,请使用

       @Override
        public void onClick(View v)
        {
            if(check.isChecked())
            {
                edit.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
                Log.i(TAG, "Show password");
            }
            else
            {
                edit.setTransformationMethod(PasswordTransformationMethod.getInstance());
                Log.i(TAG, "Hide password");
