java - 没有按钮单击的TextSwitcher

Question

嗨，有人可以帮我，因为我是android studio开发的新手，需要帮助。我已经创建了一个带有按钮单击的textswitcher，但是我想添加一些修改，例如当用户建立联系或在屏幕上滑动时，它会滑动到下一个文本，而不是使用click on按钮。请您指教？

Java文件

public class NationalMediaMuseum extends Activity
{
    private TextSwitcher mSwitcher;
    Button btnNext;

    // Array of String to Show In TextSwitcher
    String textToShow[]={"Main HeadLine","Hello World ","Hello Eeveryone","New Articles","Business News","What IS New"};
    int messageCount=textToShow.length;
    // to keep current Index of text
    int currentIndex=-1;



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

        setContentView(R.layout.activity_national_media_museum);

        // get The references
        btnNext=(Button)findViewById(R.id.buttonNext);
        mSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher);

        // Set the ViewFactory of the TextSwitcher that will create TextView object when asked
        mSwitcher.setFactory(new ViewSwitcher.ViewFactory() {

            public View makeView() {
                // TODO Auto-generated method stub
                // create new textView and set the properties like clolr, size etc
                TextView myText = new TextView(NationalMediaMuseum.this);
                myText.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
                myText.setTextSize(36);
                myText.setTextColor(Color.BLUE);
                return myText;
            }
        });

        // Declare the in and out animations and initialize them
        Animation in = AnimationUtils.loadAnimation(this,android.R.anim.slide_in_left);
        Animation out = AnimationUtils.loadAnimation(this,android.R.anim.slide_out_right);

        // set the animation type of textSwitcher
        mSwitcher.setInAnimation(in);
        mSwitcher.setOutAnimation(out);

        // ClickListener for NEXT button
        // When clicked on Button TextSwitcher will switch between texts
        // The current Text will go OUT and next text will come in with specified animation
        btnNext.setonclickListener(new View.onclickListener() {

            public void onclick(View v) {
                // TODO Auto-generated method stub
                currentIndex++;
                // If index reaches maximum reset it
                if (currentIndex == messageCount)
                    currentIndex = 0;
                mSwitcher.setText(textToShow[currentIndex]);
            }
        });

    }
}

这是一个指向android开发人员页面的链接，该页面提供了有关如何使用ViewPager的详细信息，该ViewPager应该可以完全满足您的要求。这是我以前在应用程序中完成的方法。 ViewPager
