Examples with ViewConfiguration android.view.ViewConfiguration used on opensource projects

Example 1 with ViewConfiguration

use of android.view.ViewConfiguration in project Android-ObservableScrollView by ksoichiro.

the class ViewPagerTab2Activity method onCreate.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_viewpagertab2);
    setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
    ViewCompat.setElevation(findViewById(R.id.header), getResources().getDimension(R.dimen.toolbar_elevation));
    mToolbarView = findViewById(R.id.toolbar);
    mPagerAdapter = new NavigationAdapter(getSupportFragmentManager());
    mPager = (ViewPager) findViewById(R.id.pager);
    mPager.setAdapter(mPagerAdapter);
    // Padding for ViewPager must be set outside the ViewPager itself
    // because with padding, EdgeEffect of ViewPager become strange.
    final int tabHeight = getResources().getDimensionPixelSize(R.dimen.tab_height);
    findViewById(R.id.pager_wrapper).setPadding(0, getActionBarSize() + tabHeight, 0, 0);
    SlidingTabLayout slidingTabLayout = (SlidingTabLayout) findViewById(R.id.sliding_tabs);
    slidingTabLayout.setCustomTabView(R.layout.tab_indicator, android.R.id.text1);
    slidingTabLayout.setSelectedIndicatorColors(getResources().getColor(R.color.accent));
    slidingTabLayout.setDistributeEvenly(true);
    slidingTabLayout.setViewPager(mPager);
    ViewConfiguration vc = ViewConfiguration.get(this);
    mSlop = vc.getScaledTouchSlop();
    mInterceptionLayout = (TouchInterceptionFrameLayout) findViewById(R.id.container);

Example 4 with ViewConfiguration

use of android.view.ViewConfiguration in project android_frameworks_base by ParanoidAndroid.

the class PagedView method isFlingingToDelete.

/*
     * Flinging to delete - IN PROGRESS
     */

    ViewConfiguration config = ViewConfiguration.get(getContext());
    mVelocityTracker.computeCurrentVelocity(1000, config.getScaledMaximumFlingVelocity());

        // Do a quick dot product test to ensure that we are flinging upwards
        PointF vel = new PointF(mVelocityTracker.getXVelocity(), mVelocityTracker.getYVelocity());
        PointF upVec = new PointF(0f, -1f);
        float theta = (float) Math.acos(((vel.x * upVec.x) + (vel.y * upVec.y)) / (vel.length() * upVec.length()));
