因為用講解的方式有點難理解我的問題,所以小弟放上一些code,更容易讓人瞭解好了 public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ContactTimer = new Timer(); ContactsetTimerTask(); delBtn = (Button) findViewById(R.id.delBtn); delBtn.setOnClickListener(del); Intent intent2=new Intent(); intent2.setClass(MainActivity.this,fileread.class); startActivityForResult(intent2, ReadAllData); } private OnClickListener del = new OnClickListener(){ public void onClick(View v) { if (ContactTimer != null) { ContactTimer.cancel(); ContactTimer = null; } else { ContactTimer = new Timer(); ContactsetTimerTask(); } // 一樣利用AlertDialog 讓使用者輸入 + 多選功能 for(int i=0;i<names.length;i++)isChecked[i]=false; Builder DelAlertDialog = new AlertDialog.Builder(MainActivity.this); DelAlertDialog.setTitle("Del").setMultiChoiceItems( names, isChecked, onChoice) .setPositiveButton("Delete", showSelectedResult) .setNegativeButton("Discard", null).show(); } private OnMultiChoiceClickListener onChoice = new OnMultiChoiceClickListener(){ ............ } DialogInterface.OnClickListener showSelectedResult = new DialogInterface.OnClickListener(){ ............ } private void ContactsetTimerTask() { ContactTimer.schedule(new TimerTask() { @Override public void run() { Message message = new Message(); message.what = 1; ContactTimerHandler.sendMessage(message); } }, 1000, 1000); } private Handler ContactTimerHandler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); int msgId = msg.what; switch (msgId) { case 1: Intent intent=new Intent(); intent.setClass(MainActivity.this,fileread.class); startActivityForResult(intent, ReadAllData); break; default: break; } } }; public void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case ReadAllData: names= data.getExtras().getString("SDstr").split("\n"); isChecked = new boolean[names.length]; break; } } 希望放上code,能更快的解決問題,謝謝大家 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.0.248.229 ※ 編輯: fake01 來自: 123.0.248.229 (05/21 00:40) ※ 編輯: fake01 來自: 123.0.248.229 (05/21 00:44)
