Question

我正在制作一个Android应用程序，其中我已经放置了10个图像并在其上放置了触控功能但是每当我到达第10个图像时它仍在工作并返回第1个图像。我想在第10张图片或最后一张图片上停止ontouch功能。

任何人都知道这个功能吗？

这是Java代码：

public class Activity1 extends Activity implements OnTouchListener{

float downXValue;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set main.XML as the layout for this Activity
    setContentView(R.layout.main);

    // Add these two lines
    LinearLayout layMain = (LinearLayout) findViewById(R.id.layout_main);
    layMain.setOnTouchListener((OnTouchListener) this); 

    // Add a few countries to the spinner
    Spinner spinnerCountries = (Spinner) findViewById(R.id.spinner_country);
    ArrayAdapter countryArrayAdapter = new ArrayAdapter(this,
                android.R.layout.simple_spinner_dropdown_item,
                new String[] { "Canada", "USA" });
    spinnerCountries.setAdapter(countryArrayAdapter);

}

public boolean onTouch(View arg0, MotionEvent arg1) {

    // Get the action that was done on this touch event
    switch (arg1.getAction())
    {
        case MotionEvent.ACTION_DOWN:
        {
            // store the X value when the user's finger was pressed down
            downXValue = arg1.getX();
            break;
        }

        case MotionEvent.ACTION_UP:
        {
            // Get the X value when the user released his/her finger
            float currentX = arg1.getX();            

            // going backwards: pushing stuff to the right
            if (downXValue < currentX)
            {
                // Get a reference to the ViewFlipper
                 ViewFlipper vf = (ViewFlipper) findViewById(R.id.details);
                 // Set the animation
                  vf.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_out));
                  // Flip!
                  vf.showPrevious();
            }

            // going forwards: pushing stuff to the left
            if (downXValue > currentX)
            {
                // Get a reference to the ViewFlipper
                ViewFlipper vf = (ViewFlipper) findViewById(R.id.details);
                 // Set the animation
                 vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));
                  // Flip!
                 vf.showNext();
            }
            break;
        }
    }

    // if you return false, these actions will not be recorded
    return true;
}

}

这里是xml代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/layout_main"
    >

    <ViewFlipper android:id="@+id/details"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">  




         <LinearLayout

            android:layout_width="fill_parent"

            >

            <ImageView android:id="@+id/ImageView01" android:background="@drawable/eea" 
            android:layout_x="1dip" android:layout_y="1dip" 
            android:layout_height="fill_parent" android:layout_width="fill_parent"></ImageView>
        </LinearLayout> 

        <LinearLayout

            >

            <ImageView android:id="@+id/ImageView01" android:background="@drawable/ef" 
            android:layout_x="1dip" android:layout_y="1dip" 
            android:layout_height="fill_parent" android:layout_width="fill_parent"></ImageView>
        </LinearLayout> 

        <LinearLayout
               android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >

            <ImageView android:id="@+id/ImageView01" android:background="@drawable/eg" 
            android:layout_x="1dip" android:layout_y="1dip" 
            android:layout_height="fill_parent" android:layout_width="fill_parent"></ImageView>
        </LinearLayout> 

        <LinearLayout
               android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >

            <ImageView android:id="@+id/ImageView01" android:background="@drawable/eh" 
            android:layout_x="1dip" android:layout_y="1dip" 
            android:layout_height="fill_parent" android:layout_width="fill_parent"></ImageView>
        </LinearLayout> 


    </ViewFlipper>

</LinearLayout>

我在我的代码中使用了View flipper，然后在其上添加了图片。

Answer 1

对于所有其他图片，在第10张图片的onTouch()方法setFocussable("false");方法setFocussableInTouchMode("false")和{{1}} ..我猜的唯一方法..
