这是我的Java类
public void onClick(View arg0) {
String a=null;
switch(arg0.getId()){
case R.id.left:
Toast.makeText(getApplicationContext(), "Prev"+ count, Toast.LENGTH_LONG).show();
if(count==0)
prev.setEnabled(false);
else{
count--;
Toast.makeText(getApplicationContext(), "Prev", Toast.LENGTH_LONG).show();
}
break;
case R.id.right:
Toast.makeText(getApplicationContext(), "Prev"+ count, Toast.LENGTH_LONG).show();
if(count>((abc.size()/5)))
next.setEnabled(false);
else{
count++;
onClick(arg0);
}
break;
case R.id.b1:
t41.setText("t1");
tt41.setText("tt1");
a=abc.get((count*0)+0)+"";
bb1.setText(a);
}
break;
case R.id.b2:
t42.setText("t1");
tt42.setText("tt1");
a=abc.get((count*0)+1)+"";
bb2.setText(a);
}
break;
case R.id.b3:
t43.setText("t1");
tt43.setText("tt1");
a=abc.get((count*0)+2)+"";
bb3.setText(a);
}
break;
case R.id.b4:
t44.setText("t1");
tt44.setText("tt1");
a=abc.get((count*0)+3)+"";
bb4.setText(a);
}
break;
case R.id.b5:
t45.setText("t1");
tt45.setText("tt1");
a=abc.get((count*0)+4)+"";
bb5.setText(a);
}
break;
}
}
现在我想改变按钮上的文字时，我点击从列表“abc”中可用的列表中选择next和prev按钮。计数是其他类中的STATIC变量。当我点击这些值不会改变按钮。任何人都可以请帮我出这个问题..
在XML中，无论你想调用的onClick使用此代码
您是否设置了两个按钮的点击列表？ –
是的，我已经设置了它们。只是为了测试我评论他们。现在你可以检查实际的代码。 – Sekhar
是其他按钮？ –
