Android中edittext使用代码切换密文明文显示的小问题

在使用edittext的过程中,如果我们在代码中,仅仅只设置为
editText1.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
的话,会不会有任何作用的
然后这里有一个地方需要引起我们的注意,需要注意XML部分参数值在Java代码中设置时要达到相同效果可能java中参数需要由多个参数组合使用。
使用代码设置类似XML效果参数时若为达到效果应查找相关类似的参数表。

//显示方式
if (isChecked) {
//密文
mPswEdt.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
} else {
//明文
mPswEdt.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
}
使用这种方式，使用代码修改密码显示，会有一个小问题，就是显示的密码的*和原本的显示有一点差距，大小比原本的大一点点，使用起来比较难受，密码长度上去以后就会看出差距，解决也不算难，在init的时候，就直接设置一次就可以，强行全部变大，就看不出差距了。但是对于有强迫证的人来说，这种方式不算很完美。对于密码的显示问题可以使用下面这种方式。
第二种方式
//显示方式
if (isChecked) {
//显示明文
mPswEdt.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
} else {
//显示密文
mPswEdt.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
这种方式就没有问题了。
