java - 如何设置 setContentView()；去

Question

我有我的主要布局，setContentView(R.layout.activity_detail)，

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_detail);

如何在下面的代码中将布局的可见性设置为 GONE

   if (extras.get("NAME").equals("Blog")) {
        Intent blog = new Intent(DetailActivity.this, ReportActivity.class);
        blog.putExtra("URL", "url");
        blog.putExtra("filename", "Blog");
        startActivity(blog);

  // I want to Perform the operation here

        }

Answer 1

我认为您实际上是在尝试关闭当前 Activity，同时打开一个新 Activity。

您可以如下操作，无需隐藏当前 Activity 。

 Intent blog = new Intent(DetailActivity.this, ReportActivity.class);
 blog .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 blog.putExtra("URL", "url");
 blog.putExtra("filename", "Blog");
 startActivity(blog);
 finish();
