Android中的按钮列表

Question

我想在Activity中创建一个ImageButtons列表,每行有三个按钮.如果我用XML做这个(考虑到有超过100个按钮),eclipse抱怨说有很多观点.

有一个更好的方法吗？谢谢!

Answer 1

我认为你应该按钮制作按钮......就像这样

Button[] btnWord = new Button[num];
 LinearLayout linear;
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.dynamicview);
  test();
 }
 private void test() {  
  linear = (LinearLayout) findViewById(R.id.linear);
  for (int i = 0; i < btnWord.length; i++) {
   btnWord[i] = new Button(this);
   btnWord[i].setHeight(50);
   btnWord[i].setWidth(50);
   btnWord[i].setTag(i);
   btnWord[i].setOnClickListener(btnClicked);
   linear.addView(btnWord[i]);
  }
 }
 OnClickListener btnClicked = new OnClickListener() {
  @Override
  public void onClick(View v) {
   Object tag = v.getTag();
   Toast.makeText(getApplicationContext(), "clicked button", Toast.LENGTH_SHORT).show();
  }
 };

你可以改变按钮阵列的数量

Button[] btnword = new Button[num];

听起来你应该考虑使用GridView.
