Question

在我的应用程序中，我使用警告对话框显示警告消息并等待是/否。但警报对话框显示无需等待并消失。这里的代码如下所示

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Delete Macro");
            builder.setMessage(" " + mMacroName + "\n\nAre you sure ?");

            builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                   // some tasks
                   }
               });

            builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       finish();
                   }
               });

            AlertDialog dialog = builder.create();
            builder.show();

收到logcat 显示出一些泄漏

试试这个

 AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("Delete Macro");
                builder.setMessage(" " + mMacroName + "\n\nAre you sure ?");

                builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                       public void onClick(DialogInterface dialog, int id) {
                       // some tasks
                       }
                   })

                builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
                       public void onClick(DialogInterface dialog, int id) {

                       //you are finishing the activity first and trying to display          the dialog later.this your problem 
                           // comment the `finish()`    and see

                          //finish();
                       }
                   }).create();

                builder.show();

Android Alert对话框无需等待即可关闭
