在使用edittext的過程中,如果我們在代碼中,僅僅只設(shè)置為
editText1.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
的話,會不會有任何作用的
然后這里有一個地方需要引起我們的注意,需要注意XML部分參數(shù)值在Java代碼中設(shè)置時要達到相同效果可能java中參數(shù)需要由多個參數(shù)組合使用。
使用代碼設(shè)置類似XML效果參數(shù)時若為達到效果應(yīng)查找相關(guān)類似的參數(shù)表。

//顯示方式
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);
}
使用這種方式，使用代碼修改密碼顯示，會有一個小問題，就是顯示的密碼的*和原本的顯示有一點差距，大小比原本的大一點點，使用起來比較難受，密碼長度上去以后就會看出差距，解決也不算難，在init的時候，就直接設(shè)置一次就可以，強行全部變大，就看不出差距了。但是對于有強迫證的人來說，這種方式不算很完美。對于密碼的顯示問題可以使用下面這種方式。
第二種方式
//顯示方式
if (isChecked) {
//顯示明文
mPswEdt.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
} else {
//顯示密文
mPswEdt.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
這種方式就沒有問題了。
