Android對話框教程

1.1簡單提示框

1. //簡單提示框
2. private Dialog Dialog1(){
3. return new AlertDialog.Builder(XXXActivity.this).setTitle("提示").setMessage("提示內容太短").show();
4. }

1.2多個按鈕提示框

1. @Override
2. protected Dialog onCreateDialog(int id) {
3. if(id == 1){//兩個按鈕提示框
4. return new AlertDialog.Builder(XXXActivity.this)
5. .setTitle("提示").setMessage("提示內容太短")
6. .setPositiveButton("確定", new DialogInterface.OnClickListener() {
8. @Override
9. public void onClick(DialogInterface dialog, int which) {
10. // TODO Auto-generated method stub
11. dismissDialog(1);
12. }
13. })
14. .setNegativeButton("取消", new DialogInterface.OnClickListener() {
16. @Override
17. public void onClick(DialogInterface dialog, int which) {
18. // TODO Auto-generated method stub
19. dismissDialog(1);
20. }
21. }).create();
22. }else if(id == 2){//三個按鈕提示框
23. return new AlertDialog.Builder(XXXActivity.this)
24. .setTitle("提示").setMessage("哈哈哈哈")
25. .setIcon(R.drawable.ic_launcher)
26. .setPositiveButton("注冊", new DialogInterface.OnClickListener() {
28. @Override
29. public void onClick(DialogInterface dialog, int which) {
30. // TODO Auto-generated method stub
32. }
33. })
34. .setNeutralButton("找回密碼", new DialogInterface.OnClickListener() {
35. //注意這裡和下面的取消是不一樣的setNeutral.....setNegative
36. @Override
37. public void onClick(DialogInterface dialog, int which) {
38. // TODO Auto-generated method stub
40. }
41. })
42. .setNegativeButton("取消", new DialogInterface.OnClickListener() {
44. @Override
45. public void onClick(DialogInterface dialog, int which) {
46. // TODO Auto-generated method stub
48. }
49. }).create();
50. }else if(id ==4){ //圓形進度框
51. ProgressDialog dialog = new ProgressDialog(XXXActivity.this);
52. dialog.setTitle("正在下載歌曲...");
53. dialog.setMessage("請稍候......");
54. return dialog;
55. }
57. return super.onCreateDialog(id);
58. }

1.3自定義對話框

命名xxxx.xml文件是我們想要自定義的風格

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:Android="http://schemas.android.com/apk/res/android"
3. android:layout_width="fill_parent"
4. android:layout_height="wrap_content"
5. android:orientation="vertical" >
6. <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"
7. android:layout_marginLeft="20dip" android:layout_marginRight="20dip"
8. android:text="請輸入..." android:gravity="left"
9. android:textAppearance="?android:attr/textAppearanceMedium"/>
10. <EditText android:id="@+id/testdaysnum"
11. android:layout_height="wrap_content"
12. android:layout_width="fill_parent"
13. android:layout_marginLeft="20dip"
14. android:layout_marginRight="20dip"
15. android:scrollHorizontally="true"
16. android:autoText="false"
17. android:capitalize="none"
18. android:gravity="fill_horizontal"
19. android:textAppearance="?android:attr/textAppearanceMedium"
20. />
22. </LinearLayout>

1. //自定義Dialog
2. LayoutInflater factory = LayoutInflater.from(XXXActivity.this);
3. final View testDialogView = factory.inflate(R.layout.xxxx, null);
4. EditText edit_GetDayNum = (EditText)testDialogView.findViewById(R.id.testdaysnum);
5. new AlertDialog.Builder(XXXActivity.this)
6. .setTitle("提示")
7. .setView(testDialogView)
8. .setPositiveButton("確定", new DialogInterface.OnClickListener() {
10. @Override
11. public void onClick(DialogInterface dialog, int which) {
12. // TODO Auto-generated method stub
14. Toast.makeText(XXXActivity.this, "請等待...", Toast.LENGTH_LONG).show();
15. }
16. }).create().show();

1. ProgressDialog m_Dialog = ProgressDialog.show(XXXActivity.this, "請等待...", "請稍候....",true);

1.5Toast

1. Toast.makeText(XXXActivity.this, "請等待...", Toast.LENGTH_LONG).show();

1. Dialog dialog = new Dialog(XXXActivity.this);
2. Window window = dialog.getWindow();
3. window.setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
4. WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
5. dialog.show();
