AlertDialog的五种样式

作者:互联网

建立DialogActivity.java文件:

  1 public class DialogActivity extends AppCompatActivity {
  2     private Button BtnDialog1,BtnDialog2,BtnDialog3,BtnDialog4,BtnDialog5;
  3     @Override
  4     protected void onCreate(Bundle savedInstanceState) {
  5         super.onCreate(savedInstanceState);
  6         setContentView(R.layout.activity_dialog);
  7         BtnDialog1=findViewById(R.id.btn_dialog1);
  8         BtnDialog2=findViewById(R.id.btn_dialog2);
  9         BtnDialog3=findViewById(R.id.btn_dialog3);
 10         BtnDialog4=findViewById(R.id.btn_dialog4);
 11         BtnDialog5=findViewById(R.id.btn_dialog5);
 12         OnClick onClick=new OnClick();
 13         BtnDialog1.setOnClickListener(onClick);
 14         BtnDialog2.setOnClickListener(onClick);
 15         BtnDialog3.setOnClickListener(onClick);
 16         BtnDialog4.setOnClickListener(onClick);
 17         BtnDialog5.setOnClickListener(onClick);
 18     }
 19 
 20     class OnClick implements View.OnClickListener{
 21         @Override
 22         public void onClick(View view) {
 23             switch(view.getId()){
 24                 case R.id.btn_dialog1:
 25                     AlertDialog.Builder builder=new AlertDialog.Builder(DialogActivity.this);
 26                     builder.setTitle("请问:").setMessage("天哥的课程怎么样?")
 27                             .setIcon(R.drawable.zhanghao)//加图标
 28                             .setPositiveButton("不错", new DialogInterface.OnClickListener() {
 29                                 @Override
 30                                 public void onClick(DialogInterface dialogInterface, int i) {
 31                                     //ToastUtil.showMsg(DialogActivity.this,"诚实的很");
 32                                     Toast.makeText(DialogActivity.this, "有眼光", Toast.LENGTH_SHORT).show();
 33                                 }
 34                             }).setNeutralButton("一般", new DialogInterface.OnClickListener() {
 35                         @Override
 36                         public void onClick(DialogInterface dialogInterface, int i) {
 37                             Toast.makeText(DialogActivity.this, "要不再看看?", Toast.LENGTH_SHORT).show();
 38                         }
 39                     }).setNegativeButton("不好", new DialogInterface.OnClickListener() {
 40                         @Override
 41                         public void onClick(DialogInterface dialogInterface, int i) {
 42                             Toast.makeText(DialogActivity.this, "请注意言辞", Toast.LENGTH_SHORT).show();
 43                         }
 44                     }).show();//默认样式
 45                     break;
 46                 case R.id.btn_dialog2:
 47                     String[] array2=new String[]{"女","男"};
 48                     AlertDialog.Builder builder2=new AlertDialog.Builder(DialogActivity.this);
 49                     builder2.setTitle("您的性别是:").setItems(array2, new DialogInterface.OnClickListener() {
 50                         @Override
 51                         public void onClick(DialogInterface dialogInterface, int i) {

 53                         }
 54                     }).show();

 59                     builder3.setTitle("您的性别是:").setSingleChoiceItems(array3, 0, new DialogInterface.OnClickListener() {
 60                         //其中0是默认选择的位置
 61                         @Override
 62                         public void onClick(DialogInterface dialogInterface, int i) {
 63                             Toast.makeText(DialogActivity.this, array3[i], Toast.LENGTH_SHORT).show();
 64                             dialogInterface.dismiss();//设置了这个点击选项后就会消失
 65                         }
 66                     }).setCancelable(false).show();//单选框样式,.setCancelable(false)这个点其他任何位置警示框都不会消失
 67                     break;
 68                 case R.id.btn_dialog4:
 69                     String[] array4=new String[]{"抽烟","喝酒","烫头"};
 70                     boolean[] isSelected=new boolean[]{false,true,true};//默认选中哪个哪个就是true
 71                     AlertDialog.Builder builder4=new AlertDialog.Builder(DialogActivity.this);
 72                     builder4.setTitle("您的兴趣是:").setMultiChoiceItems(array4, isSelected, new DialogInterface.OnMultiChoiceClickListener() {
 73                         @Override
 74                         public void onClick(DialogInterface dialogInterface, int i, boolean b) {
 75                             Toast.makeText(DialogActivity.this, array4[i]+":"+b, Toast.LENGTH_SHORT).show();
 76                         }
 77                     }).setPositiveButton("确定", new DialogInterface.OnClickListener() {
 78                         @Override
 79                         public void onClick(DialogInterface dialogInterface, int i) {
 80                             //没有点击事件
 81                         }
 82                     }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
 83                         @Override
 84                         public void onClick(DialogInterface dialogInterface, int i) {
 85                             //没有点击事件
 86                         }
 87                     }).show();//多选框
 88                     break;
 89                 case R.id.btn_dialog5:
 90                     AlertDialog.Builder builder5=new AlertDialog.Builder(DialogActivity.this);
 91                     View view1=LayoutInflater.from(DialogActivity.this).inflate(R.layout.layout_dialog,null);
 92                     EditText etUsername=view1.findViewById(R.id.et_username);
 93                     EditText stPassword=view1.findViewById(R.id.et_password);
 94                     Button btnLogin=view1.findViewById(R.id.btn_login);
 95                     btnLogin.setOnClickListener(new View.OnClickListener() {
 96                         @Override
 97                         public void onClick(View view) {
 98                             //没有点击事件
 99                         }
100                     });
101                     builder5.setTitle("请先进行登录").setView(view1).show();//自定义警示框
102                     break;
103             }
104         }
105     }
106 }

对应的activity_dialog.xml文件:

 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     android:layout_width="match_parent"
 3     android:layout_height="match_parent"
 4     android:orientation="vertical">
 5     <Button
 6         android:id="@+id/btn_dialog1"
 7         android:layout_width="match_parent"
 8         android:layout_height="wrap_content"
 9         android:text="style1"
10         android:textAllCaps="false"/>
11     <Button
12         android:id="@+id/btn_dialog2"
13         android:layout_width="match_parent"
14         android:layout_height="wrap_content"
15         android:text="style2"
16         android:textAllCaps="false"/>
17     <Button
18         android:id="@+id/btn_dialog3"
19         android:layout_width="match_parent"
20         android:layout_height="wrap_content"
21         android:text="style3"
22         android:textAllCaps="false"/>
23     <Button
24         android:id="@+id/btn_dialog4"
25         android:layout_width="match_parent"
26         android:layout_height="wrap_content"
27         android:text="style4"
28         android:textAllCaps="false"/>
29     <Button
30         android:id="@+id/btn_dialog5"
31         android:layout_width="match_parent"
32         android:layout_height="wrap_content"
33         android:text="style5"
34         android:textAllCaps="false"/>
35 </LinearLayout>

 

还有设置样式的layout_dialog.xml文件:

 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     android:layout_width="match_parent"
 3     android:layout_height="match_parent"
 4     android:orientation="vertical"
 5     android:padding="20dp">
 6     <EditText
 7         android:id="@+id/et_username"
 8         android:layout_width="match_parent"
 9         android:layout_height="wrap_content"
10         android:hint="username"
11         android:maxLines="1"/>
12     <EditText
13         android:id="@+id/et_password"
14         android:layout_width="match_parent"
15         android:layout_height="wrap_content"
16         android:hint="password"
17         android:inputType="textPassword"
18         android:maxLines="1"
19         android:layout_marginTop="10dp"/>
20     <Button
21         android:id="@+id/btn_login"
22         android:layout_width="match_parent"
23         android:layout_height="wrap_content"
24         android:text="login"
25         android:textAllCaps="false"
26         android:layout_marginTop="10dp"/>
27 </LinearLayout>
