Question

所以我在android上的菜单中查找标题时出现问题。我试图做的是创建一个“if”，它将获得文本“Home”并将其更改为“asdas”但由于某种原因它不会进入“if”。我认为它很容易解决，但我必须遗漏一些东西。

感谢所有

if(menu.getHeaderType() == HeaderType.HeaderType_CATEGORY) {
                frameCategory.setVisibility(View.VISIBLE);
                Spanned title = Html.fromHtml(MainActivity.this.getResources().getString(menu.getMenuResTitle()));
                TextView tvTitle = (TextView) v.findViewById(R.id.tvTitle);

                //This is the if that should change home to asdas
                if (tvTitle.getText() == "Home"){
                    tvTitle.setText("asdas");
                    Log.v("myApp", "ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA" );

                }else {

                    tvTitle.setText(title);

                }
                ImageView imgViewIcon = (ImageView) v.findViewById(R.id.imgViewIcon);
                imgViewIcon.setImageResource(menu.getMenuResIconSelected());
            }

这是错误的地方：

if (tvTitle.getText() == "HOME")
//----------^^^^^^^^^------------
{
    tvTitle.setText("asdas");

    Log.v("myApp", "ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA" );

 }

这是应该：

的方式

if (tvTitle.getText().toString() == "HOME")
//-------------------^^^^^^^^^^^-----------
{
    tvTitle.setText("asdas");
    Log.v("myApp", "ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA - ASDA" );

}
