最终代码如下：

if(imgEye.getText()==mcontext.getString(R.string.post_img_view)){
	editPassword.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
	imgEye.setText(mcontext.getText(R.string.login_no_eye));
}else{
	imgEye.setText(mcontext.getText(R.string.post_img_view));
	editPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
//设置光标位置
editPassword.setSelection(editPassword.getText().toString().length());
