java - Android 对话框和内存

Question

案例 1:

public class NewEntryActivity 
{

  public void onCreate(Bundle savedInstanceState)
    {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.xxxx);


    //my_button_1 
        my_button_1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            final Dialog dialog = new Dialog(NewEntryActivity.this);

              dialog.setContentView(R.layout.abcabc);

              dialog.show(); 

              // On click of OK button in this dialog it will DISMISS the dialog. ( NOT remove )

            }
            }

    //my_button_2
        my_button_2.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            final Dialog dialog = new Dialog(NewEntryActivity.this);

              dialog.setContentView(R.layout.xyzxyz);

              dialog.show(); 

              // On click of OK button in this dialog it will DISMISS the dialog. ( NOT remove )

            }


            }

    }
}

案例 2:

public class NewEntryActivity 
{

  public void onCreate(Bundle savedInstanceState)
    {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.xxxx);


        final Dialog dialog1 = new Dialog(NewEntryActivity.this);
        final Dialog dialog2 = new Dialog(NewEntryActivity.this);

        dialog1.setContentView(R.layout.abcabc);
        dialog2.setContentView(R.layout.xyzxyz);

        //my_button_1 
        my_button_1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

              dialog1.show(); 

            }
            }

    }


}

在案例 2 中，我的对话框中已经设置了内容 View 。只需单击按钮即可显示/关闭。

所以我的问题是，第一种情况会释放一些内存，还是会产生同样的效果？

Answer 1

这仅取决于您的应用消耗了多少内存，尤其是在此 Activity 中，但情况 1 似乎不错。
