用java创建imageView组件

Posted 2020-10-06 喂鲨鱼

        setContentView(R.layout.activity_main);
        //获得id为ll的线性布局
        LinearLayout layout=(LinearLayout)this.findViewById(R.id.ll);
        //创建imageView的组件
        final ImageView imge=new ImageView(MainActivity.this);
        imge.setImageResource(images[currentImage]);
        //将imageView组件添加到id=ll的线性布局里去
        layout.addView(imge);
        //注册事件监听器
        imge.setOnClickListener(new View.OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                
            }
        });

ps

之前定义了图片数组

int []images=new int[] {
            R.drawable.list1,
            R.drawable.list2,
            R.drawable.list3,
            R.drawable.list4,
            R.drawable.list5,
            R.drawable.list6,
            R.drawable.list7,
            R.drawable.list8,
    };
int currentImage=0;
