Android多按钮对话框:如何实现切换情况

Question

我怎么能把OnClickListener在开关情况(或如果/else)如果我的对话框有多个按钮如下:

我想让用户选择值为分配静态变量输入

public class ActivityInput extends Activity {
    public static String input;
    public void selectValue (final int x) {
        btn = (Button) findViewById(x);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
           //Display dialog with 3 button for user to select the values
                final Dialog dialog1 = new Dialog(input.this);
                dialog1.setTitle("Select a Number");
                dialog1.setContentView(R.layout.dialog);
                dialog1.show();

                button1 = (Button) dialog1.findViewById(R.id.val1);
                button1.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Button p1_btn = (Button) findViewById(x);
                        input = "1";
                        p1_btn.setText("1");
                        dialog1.dismiss();
                    }
                });
                button2 = (Button) dialog1.findViewById(R.id.val2);
                button2.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Button p1_btn = (Button) findViewById(x);
                        input = "2";
                        p1_btn.setText("2");
                        dialog1.dismiss();
                    }
                });
                button3 = (Button) dialog1.findViewById(R.id.val3);
                button3.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Button p1_btn = (Button) findViewById(x);
                        input = "3";
                        p1_btn.setText("2");
                        dialog1.dismiss();
                    }
                });
            }
        });
    }
}

希望您的指导能尽快帮助我!

非常感谢。

无需xml的简单解决方案:

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Title");
builder.setItems(new CharSequence[]
        {"button 1", "button 2", "button 3", "button 4"},
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // The 'which' argument contains the index position
                // of the selected item
                switch (which) {
                    case 0:
                        Toast.makeText(context, "clicked 1", 0).show();
                        break;
                    case 1:
                        Toast.makeText(context, "clicked 2", 0).show();
                        break;
                    case 2:
                        Toast.makeText(context, "clicked 3", 0).show();
                        break;
                    case 3:
                        Toast.makeText(context, "clicked 4", 0).show();
                        break;
                }
            }
        });
builder.create().show();

public void verticalAlert (){
String[] array = {"item01","item02","item03"};
AlertDialog.Builder builder = new AlertDialog.Builder(MyActivity.this);
builder.setTitle("Test")
  .setItems(array, new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int which) {
      // The 'which' argument contains the index position
      // of the selected item
        switch (which) {
    case 0:         
        // case item 1 do...
        break;          
    case 1:         
        //  case item 2 do...                   
        break;
    case 2:         
        //  case item 3 do...                   
        break;
    }
  }
});
builder.show();
}
