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

Question

这是一个奇怪的案例，最近才引起我的注意。我有一个 Activity 在创建时显示 AlertDialog 以警告用户要完成他们需要重新启动的过程。在我的设备 (Galaxy Nexus) 上，它显示得很好。最近才引起我的注意，在许多其他设备上它只显示几个字就被切断了。

        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();

与其使用 setMessage()，不如尝试 setView()，提供您自己的 TextView，您可以在其中控制显示的行数显示。
