Android开发实现的图片点击切换功能示例

public class MainActivity extends AppCompatActivity {  //定义一个访问图片的数组  int[] images = new int[]{      R.drawable.java,      R.drawable.javaee,      R.drawable.swift,      R.drawable.ajax,      R.drawable.html,  };  //用于图片切换  int currenImg = 0;  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    //获取Linearlayout布局容器    LinearLayout main = (LinearLayout) findViewById(R.id.root);    //创建ImageView组件    final ImageView image = new ImageView(this);    //将ImageView组建添加到linearlayout布局中    main.addView(image);    //初始化显示第一张图片    image.setImageResource(images[0]);    image.setOnClickListener(new View.OnClickListener() {      @Override      public void onClick(View v) {        image.setImageResource(images[++currenImg % images.length]);      }    });  }}
