Android 分享按钮最后的调整

Question

大家好，我有一个按钮，我试图让用户分享由我应用程序中的三个轮子创建的特定句子，这是我到目前为止的代码：

 private void mixWheel(int id) {
    WheelView wheel = getWheel(id);
    wheel.scroll(-25 + (int) (Math.random() * 50), 2000);

    private String getWheelValue(int id) {
        WheelView wheel = getWheel(R.id.passw_1);
        int index = wheel.getCurrentItem();
        ((ArrayWheelAdapter<String>) wheel.getViewAdapter()).getItemText(index).toString();
        String values = getWheelValue(R.id.passw_1) + " " + getWheelValue(R.id.passw_2) + " " + getWheelValue(R.id.passw_3);
        return values;

        Button share = (Button) findViewById(R.id.tweet);
        share.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                emailIntent.setType("text/plain");
                emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getResources().getString(R.string.Subject));
                emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, getResources().getString(R.string.Message));
                startActivity(emailIntent);

            }
        });

问题出在“wheel.scroll(-25 + (int) (Math.random() * 50), 2000);"

我收到此错误“语法错误，插入“}”以完成 MethodBody”

如果我将其放在该行代码之后，则会出现错误 “按钮共享 = (按钮) findViewById(R.id.tweet);”

说法：无法访问的代码 使用 qcik 修复“删除”，但这只会删除该行代码之后的所有内容，我已在下面发布了完整的代码，以防万一。提前致谢。

    public class PasswActivity extends Activity {

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



    setContentView(R.layout.passw_layout);
initWheel(R.id.passw_1, new String[] { "You", "Me", "Us" });
initWheel(R.id.passw_2, new String[] { "Are", "Going", ""Went });
initWheel(R.id.passw_3, new String[] { "There", "Here", ""Away });




    Button mix = (Button) findViewById(R.id.btn_mix);
    mix.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            mixWheel(R.id.passw_1);
            mixWheel(R.id.passw_2);
            mixWheel(R.id.passw_3);

        }
    });

}

// Wheel scrolled flag
private boolean wheelScrolled = false;

// Wheel scrolled listener
OnWheelScrollListener scrolledListener = new OnWheelScrollListener() {
    public void onScrollingStarted(WheelView wheel) {
        wheelScrolled = true;

        wheelScrolled = false;

    }

        return values;

        Button share = (Button) findViewById(R.id.tweet);
        share.setOnClickListener(new View.OnClickListener() {

Answer 1

为什么你的 getWheelValue() 方法在 mixWheel 内部？尝试像这样将其移到 mixWheel 之外，然后重新组织您的调用，

private void mixWheel(int id) {
    WheelView wheel = getWheel(id);
    wheel.scroll(-25 + (int) (Math.random() * 50), 2000);




 }

private String getWheelValue(int id) {
        WheelView wheel = getWheel(R.id.passw_1);
        int index = wheel.getCurrentItem();
        ((ArrayWheelAdapter<String>) wheel.getViewAdapter()).getItemText(index).toString();
        String values = getWheelValue(R.id.passw_1) + " " + getWheelValue(R.id.passw_2) + " " + getWheelValue(R.id.passw_3);
        return values;

        Button share = (Button) findViewById(R.id.tweet);
        share.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.setType("text/plain");
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getResources().getString(R.string.Subject));
            emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, getResources().getString(R.string.Message));
            startActivity(emailIntent);

        }
    });

}

我什至不确定这是否是有效的语法（方法中的方法） - 如果我错了，有人会纠正我。
