今天我用自己写的一个Demo 和大家详细介绍一个Android中的对话框的使用技巧。?





1.确定取消对话框

对话框中有2个按钮?? 通过调用 setPositiveButton 方法 和 setNegativeButton 方法 可以设置按钮的显示内容以及按钮的监听事件。
我们使用AlerDialog 创建对话框

view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???

使用builder设置对话框的title button icon 等等

view plain
  1. builder.setIcon(R.drawable.icon);??
  2. ???????builder.setTitle("你确定要离开吗？");??
  3. ???????builder.setPositiveButton("确定",?new?DialogInterface.OnClickListener()?{??
  4. ???????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  5. ???????????????//这里添加点击确定后的逻辑??
  6. ???????????????showDialog("你选择了确定");??
  7. ???????????}??
  8. ???????});??
  9. ???????builder.setNegativeButton("取消",?new?DialogInterface.OnClickListener()?{??
  10. ???????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  11. ???????????????//这里添加点击确定后的逻辑??
  12. ???????????????showDialog("你选择了取消");??
  13. ???????????}??
  14. ???????});??
  15. ???????builder.create().show();??

??这个dialog用于现实onClick后监听的内容信息

view plain
  1. private?void?showDialog(String?str)?{??
  2. w?AlertDialog.Builder(MainDialog.this)??
  3. ?????.setMessage(str)??
  4. ?????.show();??
  5. }??



2.多个按钮信息框



view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???????????
  2. builder.setIcon(R.drawable.icon);??
  3. builder.setTitle("投票");??
  4. builder.setMessage("您认为什么样的内容能吸引您？");??
  5. builder.setPositiveButton("有趣味的",?new?DialogInterface.OnClickListener()?{??
  6. ????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  7. ????????showDialog("你选择了有趣味的");??
  8. ????}??
  9. });??
  10. builder.setNeutralButton("有思想的",?new?DialogInterface.OnClickListener()?{??
  11. ????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  12. ????????showDialog("你选择了有思想的");??????????????????????
  13. ????}??
  14. });??
  15. builder.setNegativeButton("主题强的",?new?DialogInterface.OnClickListener()?{??
  16. ????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  17. ????????showDialog("你选择了主题强的");????
  18. ????}??
  19. });??
  20. builder.create().show();??




3.列表框



这个数组用于列表选择

view plain
  1. final?String[]?mItems?=?{"item0","item1","itme2","item3","itme4","item5","item6"};??




view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???
  2. ????????builder.setTitle("列表选择框");??
  3. ????????builder.setItems(mItems,?new?DialogInterface.OnClickListener()?{??
  4. ????????????public?void?onClick(DialogInterface?dialog,?int?which)?{??
  5. ????????????????//点击后弹出窗口选择了第几项??
  6. ????????????????showDialog("你选择的id为"?+?which?+?"?,?"?+?mItems[which]);??
  7. ????????????}??
  8. ????????});??
  9. ????????builder.create().show();??



4.单项选择列表框


mSingleChoice 用于记录单选中的ID

view plain
  1. int?mSingleChoiceID?=?-1;??
view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???
  2. ??
  3. mSingleChoiceID?=?-1;??
  4. builder.setIcon(R.drawable.icon);??
  5. ????builder.setTitle("单项选择");??
  6. ????builder.setSingleChoiceItems(mItems,?0,?new?DialogInterface.OnClickListener()?{??
  7. ????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  8. ????????????????mSingleChoiceID?=?whichButton;??
  9. ????????????????showDialog("你选择的id为"?+?whichButton?+?"?,?"?+?mItems[whichButton]);??
  10. ????????}??
  11. ????});??
  12. ????builder.setPositiveButton("确定",?new?DialogInterface.OnClickListener()?{??
  13. ????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  14. ????????????if(mSingleChoiceID?>?0)?{??
  15. ????????????showDialog("你选择的是"?+?mSingleChoiceID);??
  16. ????????????}??
  17. ????????}??
  18. ????});??
  19. ????builder.setNegativeButton("取消",?new?DialogInterface.OnClickListener()?{??
  20. ????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  21. ??
  22. ????????}??
  23. ????});??
  24. ???builder.create().show();??




5.进度条框



点击进度条框按钮后 开启一个线程计算读取的进度 假设读取结束为 100
Progress在小于100的时候一直在线程中做循环++ 只到读取结束后，停止线程。
view plain
  1. ??????????mProgressDialog?=?new?ProgressDialog(MainDialog.this);??
  2. ?????mProgressDialog.setIcon(R.drawable.icon);??
  3. ?????mProgressDialog.setTitle("进度条窗口");??
  4. ?????mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);??
  5. ?????mProgressDialog.setMax(MAX_PROGRESS);??
  6. ?????mProgressDialog.setButton("确定",?new?DialogInterface.OnClickListener()?{??
  7. ?????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  8. ?????????????//这里添加点击后的逻辑??
  9. ?????????}??
  10. ?????});??
  11. ?????mProgressDialog.setButton2("取消",?new?DialogInterface.OnClickListener()?{??
  12. ?????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  13. ?????????????//这里添加点击后的逻辑??
  14. ?????????}??
  15. ?????});??
  16. ?????mProgressDialog.show();??
  17. ?????new?Thread(this).start();??
  18. ??
  19. ic?void?run()?{??
  20. int?Progress?=?0;??
  21. while(Progress?<?MAX_PROGRESS)?{??
  22. try?{??
  23. ????Thread.sleep(100);??
  24. ????Progress++;????
  25. ????mProgressDialog.incrementProgressBy(1);??
  26. }?catch?(InterruptedException?e)?{??
  27. ????//?TODO?Auto-generated?catch?block??
  28. ????e.printStackTrace();??
  29. }??
  30. ???
  31. }??


6.多项选择列表框




MultiChoiceID 用于记录多选选中的id号 存在ArrayList中
选中后 add 进ArrayList
取消选中后 remove 出ArrayList。

view plain
  1. ArrayList?<Integer>MultiChoiceID?=?new?ArrayList?<Integer>();??

view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???
  2. ??
  3. MultiChoiceID.clear();??
  4. builder.setIcon(R.drawable.icon);??
  5. ????builder.setTitle("多项选择");??
  6. ????builder.setMultiChoiceItems(mItems,??
  7. ????????????new?boolean[]{false,?false,?false,?false,?false,?false,?false},??
  8. ????????????new?DialogInterface.OnMultiChoiceClickListener()?{??
  9. ????????????????public?void?onClick(DialogInterface?dialog,?int?whichButton,??
  10. ????????????????????????boolean?isChecked)?{??
  11. ???????????????????if(isChecked)?{??
  12. ???????????????????????MultiChoiceID.add(whichButton);??
  13. ???????????????????????showDialog("你选择的id为"?+?whichButton?+?"?,?"?+?mItems[whichButton]);??
  14. ???????????????????}else?{??
  15. ???????????????????????MultiChoiceID.remove(whichButton);??
  16. ???????????????????}??
  17. ??????????????????????
  18. ????????????????}??
  19. ????????????});??
  20. ????builder.setPositiveButton("确定",?new?DialogInterface.OnClickListener()?{??
  21. ????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  22. ????????????String?str?=?"";??
  23. ????????????int?size?=?MultiChoiceID.size();??
  24. ????????????for?(int?i?=?0?;i?<?size;?i++)?{??
  25. ????????????str+=?mItems[MultiChoiceID.get(i)]?+?",?";??
  26. ????????????}??
  27. ????????????showDialog("你选择的是"?+?str);??
  28. ????????}??
  29. ????});??
  30. ????builder.setNegativeButton("取消",?new?DialogInterface.OnClickListener()?{??
  31. ????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  32. ??
  33. ????????}??
  34. ????});??
  35. ???builder.create().show();??


7.自定义布局


讲到自定义布局我就得多说一说了，为什么要多说一说呢？?
其实自定义布局在Android的开发中非常重要 因为它能让开发者做出自己五彩缤纷的Activity 而不用去使用系统枯燥的界面。

自定义dialog有什么好处？

比如我们在开发过长当中 要通过介绍系统发送的一个广播弹出一个dialog . 但是dialog必需是基于activity才能呈现出来 如果没有activity 的话 程序就会崩溃。所以我们可以写一个自定义的 dialog 把它定义成一个activity
这样我们收到一条打开dialog的广播后 直接启动这个 activity? 程序正常运行~~?

这就是自定义dialog的好处。

注明：下面这个例子只是写了自定义dialog 没有把它单独的写在一个activity中 如果须要的话 可以自己改一下。
view plain
  1. AlertDialog.Builder?builder?=?new?AlertDialog.Builder(MainDialog.this);???
  2. ?LayoutInflater?factory?=?LayoutInflater.from(this);??
  3. ?final?View?textEntryView?=?factory.inflate(R.layout.test,?null);??
  4. ?????builder.setIcon(R.drawable.icon);??
  5. ?????builder.setTitle("自定义输入框");??
  6. ?????builder.setView(textEntryView);??
  7. ?????builder.setPositiveButton("确定",?new?DialogInterface.OnClickListener()?{??
  8. ?????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  9. ???????????
  10. ?????????EditText?userName?=?(EditText)?textEntryView.findViewById(R.id.etUserName);??
  11. ?????????EditText?password?=?(EditText)?textEntryView.findViewById(R.id.etPassWord);??
  12. ?????????showDialog("姓名?："??+?userName.getText().toString()??+?"密码："?+?password.getText().toString()?);??
  13. ?????????}??
  14. ?????});??
  15. ?????builder.setNegativeButton("取消",?new?DialogInterface.OnClickListener()?{??
  16. ?????????public?void?onClick(DialogInterface?dialog,?int?whichButton)?{??
  17. ??
  18. ?????????}??
  19. ?????});??
  20. ???builder.create().show();??



view plain
  1. <span?style="color:#000000;"><?xml?version="1.0"?encoding="utf-8"?>??
  2. <RelativeLayout?xmlns:android="http://schemas.android.com/apk/res/android"??
  3. android:layout_height="wrap_content"???
  4. android:layout_width="wrap_content"??
  5. android:orientation="horizontal"??
  6. android:id="@+id/dialog">??
  7. <LinearLayout??
  8. android:layout_height="wrap_content"???
  9. android:layout_width="wrap_content"??
  10. android:orientation="horizontal"??
  11. android:id="@+id/dialogname">??
  12. ??
  13. <TextView?android:layout_height="wrap_content"??
  14. ???android:layout_width="wrap_content"??
  15. ??android:id="@+id/tvUserName"???
  16. ??android:text="姓名："?/>??
  17. <EditText?android:layout_height="wrap_content"??
  18. ??android:layout_width="wrap_content"???
  19. ??android:id="@+id/etUserName"???
  20. ??android:minWidth="200dip"/>??
  21. </LinearLayout>????
  22. <LinearLayout??
  23. android:layout_height="wrap_content"???
  24. android:layout_width="wrap_content"??
  25. android:orientation="horizontal"??
  26. android:id="@+id/dialognum"??
  27. ?android:layout_below="@+id/dialogname"??
  28. >??
  29. ??<TextView?android:layout_height="wrap_content"??
  30. ???android:layout_width="wrap_content"??
  31. ??android:id="@+id/tvPassWord"???
  32. ??android:text="密码："?/>??
  33. <EditText?android:layout_height="wrap_content"??
  34. ??android:layout_width="wrap_content"???
  35. ??android:id="@+id/etPassWord"???
  36. ??android:minWidth="200dip"/>??
  37. ?</LinearLayout>????
  38. ??</RelativeLayout></span>??

8.读取进度框

显示一个正在转圈的进度条loading

view plain
  1. mProgressDialog?=?new?ProgressDialog(this);??
  2. ?mProgressDialog.setTitle("读取ing");??
  3. ?mProgressDialog.setMessage("正在读取中请稍候");??
  4. ?mProgressDialog.setIndeterminate(true);??
  5. ?mProgressDialog.setCancelable(true);??
  6. ?mProgressDialog.show();??
