Question

我有一个警报对话框，在进入活动之前弹出窗口。这是一个警告对话框，其中包含Don't Show this again的chechbox。我添加了一个读取所有术语的mp3文件。我尝试了所有可能的东西，它没有用。这就是我想要做的。

单击I Agree按钮时，应停止正在播放的声音文件。
当用户点击时不再显示此复选框时，再次输入活动后声音不会播放。

每一条线索都会受到极大的关注。 Thnx提前。

    protected void onResume() {
        AlertDialog.Builder warning1 =     new AlertDialog.Builder(this);
        LayoutInflater warning1Inflater =     LayoutInflater.from(this);
        View myLayout = warning1Inflater.inflate(R.layout.warning_layout, null);
        final CheckBox dontShowAgain = (CheckBox) myLayout.findViewById(R.id.skip);
         warning1 .setCancelable(false); 
         warning1 .setView(myLayout);
         warning1 .setTitle("Warning!");


        MediaPlayer mp = MediaPlayer.create(StartDialog.this,R.raw.terms);
        mp.start();


   warning1 .setIcon(R.drawable.alert1);
         warning1 .setPositiveButton("I Agree", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    String checkBoxResult = "NOT checked";
                    if (dontShowAgain.isChecked())
                        checkBoxResult = "checked";
                        String PREFS_NAME = null;
                        SharedPreferences settings =     getSharedPreferences(PREFS_NAME, 0);
                        SharedPreferences.Editor editor = settings.edit();
                    editor.putString("skipMessage", checkBoxResult);

                    editor.commit();

    MediaPlayer mp = MediaPlayer.create(StartDialog.this,R.raw.terms);
        mp.stop();


      return;

                }
            });


            String PREFS_NAME = null;
            SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
            String skipMessage = settings.getString("skipMessage", "NOT checked");
        if (!skipMessage.equals("checked"))
             warning1 .show();

        super.onResume();

你应该实现这个。

dontShowAgain.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
                boolean isChecked) {
            // TODO Auto-generated method stub
            switch (buttonView.getId()) {
            case R.id.checkBox:
                checkBoxResult = "checked";
                String PREFS_NAME = "";
                SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
                SharedPreferences.Editor editor = settings.edit();
                editor.putString("skipMessage", checkBoxResult);
                editor.commit();
                break;
            }
        }
    });

点击OK按钮，您必须关闭Dialog。

现在您可以通过

进行检查

  SharedPreferences sp = getSharedPreferences("PREFS_NAME", 0);

  boolean hasBeenChecked = sp.getBoolean("skipMessage", false);
  if (!hasBeenChecked) {
                show your dialog here
  } else {
                // do your stuff here
  }
