我寫這樣的文章都是為了快速迭代，所以都寫的比較簡單，諒解

此類支持任意Model對象，該對象需要重寫toString()

        this.setCancelable(true);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState)

				dismiss();
			}
		});
    }

    private void initValues()
    {
        // 不能寫在init()中
        Window window = getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        DisplayMetrics dm = context.getResources().getDisplayMetrics();
        lp.width = dm.widthPixels;
        lp.gravity = Gravity.BOTTOM;
        window.setAttributes(lp);

    }

    private OnItemClickListener<T> onItemClickListener;

    public interface OnItemClickListener<T>
    {
        public void onItemClick(View v,T item,int position);
    }

	public void setOnItemClickListener(OnItemClickListener<T> onItemClickListener) {
		this.onItemClickListener = onItemClickListener;
	}

}

  

簡單的一個Item布局item_simple_list.xml

    
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	>
	
    <TextView 
        android:id="@+id/item_0"
        android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:paddingTop="16dp"
		android:paddingBottom="16dp"
		android:gravity="center"
		android:textColor="@color/base_text_black"
		android:textSize="@dimen/font_xbig"
		android:singleLine="true"
        />
	
</RelativeLayout>

  

附件是需要的工具類，快速生成一個ListView的代碼，可能需要Volley，如報錯，可以注釋掉不必要的代碼，不影響本例。


使用：

    
List<KeyValue> list=new ArrayList<KeyValue>();
				list.add(new KeyValue("0","繼續挑選"));
				list.add(new KeyValue("1","立即購買"));
				list.add(new KeyValue("2","配貨投遞"));
				list.add(new KeyValue("3","立即試衣"));
				
				SimpleListDialog<KeyValue> d=new SimpleListDialog<KeyValue>(context, list);
				d.setOnItemClickListener(new SimpleListDialog.OnItemClickListener<KeyValue>() {
					
					@Override
					public void onItemClick(View v, KeyValue item, int position) {
						// TODO Auto-generated method stub
						
						
					}
				});
				d.show();

  

KeyValue是個Model對象，重寫了toString()，可以是任何對象
