Android AlertDialog在某些设备上不显示整个setMessage

这是一个最近才引起我注意的奇怪情况。我有一个活动，在创建AlertDialog时会显示警告，以警告用户完成需要重新启动的过程。在我的设备上（Galaxy Nexus），它显示得很好。最近才引起我注意的是，在许多其他设备上，它只能在切断前显示几个字。Android AlertDialog在某些设备上不显示整个setMessage

 AlertDialog.Builder builder = new AlertDialog.Builder(ReportActivity.this); 
     builder.setTitle("Finished!"); 
     builder.setMessage("Due to the different storage mediums across the various Android devices this app may eb used for, " 
              +"I've decided not to force a media rescan because depending on your device, " 
              +"it may or may not even be possible. " 
              +"This means that you will need to reboot your device or unmount/mount your sdcard in the Settings app before most players will pull in all the information for the songs." 
              +"\n Please reboot or rescan before claiming that the app did not work.") 
       .setCancelable(false) 
       .setPositiveButton("Dismiss", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
            dialog.dismiss(); 
          lv1.setAdapter(new ResultsAdapter(ReportActivity.this, results)); 
        } 
       }); 

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