我正在製作一個android應用程序,其中放置了10張圖像並將ontouch功能添加到該應用程序中,但每當我到達第10張圖像時,它仍在工作並返回到第1張圖像。 我想停止第10張圖片或最後一張圖片上的ontouch功能。如何控制android中的ontouch功能?
任何人都知道這個功能?
這裏是Java代碼:
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;
}
}
這裏是XML代碼:
<?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:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<ImageView android:id="@+id/ImageView01" android:background="@drawable/eea"

</LinearLayout>
<LinearLayout

</ViewFlipper>
</LinearLayout>
我不得不使用瀏覽腳蹼在我的代碼,然後將其添加圖像。
哪裏形象的事ü在說的..? – ngesh 2011-06-14 13:38:56
對不起,我發佈錯誤的XML文件,現在我張貼rightone,你可以看到它。 – 2011-06-14 13:47:40
