Question

我知道这已被问了一百万次，但没有一次让我解决了我的问题。 onclicklistener不会激活任何按钮的代码。以下是适用于五个按钮的不同部分。

Button btnGuysMax;
Button btnGuysMedium;
Button btnEven;
Button btnGirlsMedium;
Button btnGirlsMax;

....

private void init()
{
    datasource = new BarsDataSource(this);
    datasource.open();

    Intent intent = getIntent();
    long id = intent.getLongExtra("bar_id",0);
    bar = datasource.getBarById(id);

    title = (TextView)findViewById(R.id.title);
    btnGuysMax = (Button)findViewById(R.id.btnGuysMax);
    btnGuysMedium = (Button)findViewById(R.id.btnGuysMedium);
    btnEven = (Button)findViewById(R.id.btnEven);
    btnGirlsMedium = (Button)findViewById(R.id.btnGirlsMedium);
    btnGirlsMax = (Button)findViewById(R.id.btnGirlsMax);

    ......

    btnGuysMax.setOnClickListener(this);
    btnGuysMedium.setOnClickListener(this);
    btnEven.setOnClickListener(this);
    btnGirlsMedium.setOnClickListener(this);
    btnGirlsMax.setOnClickListener(this);

    .....

    @Override
public void onClick(View view)
{
    //resetButtons();
    switch (view.getId()) {
        case R.id.btnGuysMax:
            //bar.setSexRatio(-2);
            //btnGuysMax.setBackgroundColor(guysMaxColor);
            Toast.makeText(this,"Max clicked!",Toast.LENGTH_LONG);
            break;
        case R.id.btnGuysMedium:
            bar.setSexRatio(-1);
            Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
            //btnGuysMedium.setBackgroundColor(guysMediumColor);
            break;
        case R.id.btnEven:
            bar.setSexRatio(0);
            //Toast.makeText(this,"Medium clicked!",Toast.LENGTH_LONG);
            break;
        case R.id.btnGirlsMedium:
            bar.setSexRatio(1);
            //btnGirlsMedium.setBackgroundColor(girlsMediumColor);
            break;
        case R.id.btnGirlsMax:
            bar.setSexRatio(2);
            break;

Answer 1

要显示祝酒词，您需要调用show方法。

尝试：

Toast.makeText(this,"message",Toast.LENGTH_LONG).show();

Answer 2

尝试做：

 @Override
public void onClickListener(View view)
{

而不是：

 @Override
public void onClick(View view)
{

Android按钮不会激活
