AlertDialog之常見對話框（單選對話框、多選對話框、進度條對話框）

文章出處

單選對話框，顧名思義就是只能選一項（setSingleChoiceItems(Items,)）

 1 public void click(View v){
 2         //創建對話框類
 3         AlertDialog.Builder builder = new AlertDialog.Builder(this);
 4         //定義item選項
 5         final String items[] = new String[]{"一只","兩只","三只"};
 6         builder.setTitle("沒有什么事是一只口紅解決不了的，如果有那就兩只")//設置標題
 7                 .setSingleChoiceItems(items,-1, new DialogInterface.OnClickListener() {//設置單選
 8                     @Override
 9                     public void onClick(DialogInterface dialogInterface, int i) {
10                         Toast.makeText(MainActivity.this,"你選擇了用"+items[i]+"口紅解決問題",Toast.LENGTH_SHORT).show();
11                 }
12                 }).setPositiveButton("是的", new DialogInterface.OnClickListener() {
13             @Override
14             public void onClick(DialogInterface dialogInterface, int i) {
15                 Toast.makeText(MainActivity.this,"我選擇了是",Toast.LENGTH_SHORT).show();
16             }
17         }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
18             @Override
19             public void onClick(DialogInterface dialogInterface, int i) {
20                 Toast.makeText(MainActivity.this,"我選擇了取消，因為我相信口紅解決不了",Toast.LENGTH_SHORT).show();
21             }
22         }).show();
23     }

下面是多選對話框

 1 public void click1(View v){
 2         AlertDialog.Builder builder = new AlertDialog.Builder(this);
 3         final String items[] = {"First","Second","Thrid","Fourth"};
 4         final boolean boo[] = {true,false,false,false};
 5 
 6         builder.setTitle("人生有多種選擇")
 7                 .setMultiChoiceItems(items, boo, new DialogInterface.OnMultiChoiceClickListener() {
 8                     @Override
 9                     public void onClick(DialogInterface dialogInterface, int i, boolean b) {
10                       
11                     }
12                 }).setPositiveButton("確定", new DialogInterface.OnClickListener() {
13             @Override
14             public void onClick(DialogInterface dialogInterface, int i) {
15 
16             }
17         }).show();
18     }

單選是setSingleChoiceItems()，多選是setMultiChoiceItems()，

進度條對話框

 1 public void click2(View v){
 2         final ProgressDialog pd = new ProgressDialog(this);
 3         pd.setTitle("加載");
 4         pd.setProgress(0);
 5         pd.setMax(10);
 6         pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
 7         pd.show();
 8         new Thread(){
 9             @Override
10             public void run() {
11                 super.run();
12                 for (int i=0; i<=10; i++){
13                     pd.setProgress(i);
14                     try {
15                         Thread.sleep(1000);
16                     } catch (InterruptedException e) {
17                         e.printStackTrace();
18                     }
19                 }
20             }
21         }.start();
22     }
