问题描述

我自己写代码生成动态按钮，但是不知道怎么动态实现每个按钮的点击事件.我找到了一些答案，但不适用于我的代码...请帮助我...这是我的代码

I write code to generate dynamic buttons , but I don't know how to implement click event for each button dynamically. I found some answers but not work with my code... Please help me.. This is my code

public class dynamicbuttion extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        ScrollView sv = new ScrollView(this);
        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.VERTICAL);
        sv.addView(ll);

        for(int i = 0; i < 5; i++) {
            Button btn = new Button(this);
        btn.setId(i);
        btn.setText("dynamic buttion " + i);
            ll.addView(btn);

        }

        this.setContentView(sv);

    }
}

推荐答案

Button[] btn = new Button[5];
for(int i = 0; i < 5; i++) {
    btn[i] = new Button(this);
    btn[i].setId(i);
    btn[i].setText("dynamic buttion " + i);
    ll.addView(btn[i]);
    btn[i].setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        //your desired functionality
    }
  });
}
