Essa é uma das formas de tratar eventos em uma ListView com vários itens (position, id) é diferente do evento button void onClick(View v). Desculpe se entendi errado.

http://pastebin.com/AJLL5EfiOlaá Pedro, Colequei o codigo aí!Só detalhando um pouco mais, no metodo onClick ele faz uma ação com o webservice que esta dando tudo certo, o problema é que quando eu mudo o background desse button ele muda de outros buttons tbm, mais precisamente sempre altenando um(um sim outro não).Marcelo não consegui entender direito sua sugestão.--Gleydson RochaGraduando em Ciência da Computação - UESPI

onde mlvTextMatches é o ListView
lembrando que a função listclick() esta dentro de um @Override
protected void listclick() {
mlvTextMatches.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String value = mlvTextMatches.getItemAtPosition(position).toString();
TextView v=(TextView) view.findViewById(R.id.txt);
String mytext = v.getText().toString();
sendSMS(mytext);
}
});

Você precisa identificar o item do list view para atribuir a ação ao botão.Mande o código que você fez para que possamos apontar onde pode estar o erro.Se possível use o http://pastebin.com/--Abraços,
