用了一些新控件挎狸，仿的微博界面
主要有向上滑動(dòng)圖片漸變消失，tablayout使用，用recyclerview解決1-9張圖片的顯示問題砾医，點(diǎn)擊圖片后進(jìn)入viewpager進(jìn)行縮放，保存等操作衣厘。
layout: photo
效果圖：
應(yīng)用：
設(shè)置向上滾動(dòng)消失的view
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<!-- 設(shè)置圖片-->
<!--添加一個(gè)定義了app:layout_collapseMode="parallax" 屬性的ImageView如蚜，出現(xiàn)和消失會(huì)有過度-->
<ImageView
android:id="@+id/backdrop"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="@drawable/qingdao"
app:layout_collapseMode="parallax"
/>
Toolbar自定義menu：
//actionbar導(dǎo)入menu中的設(shè)置欄
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.toolbar_actions, menu);
return super.onCreateOptionsMenu(menu);
}
TabLayout配合viewpager使用配置標(biāo)題
<!-- 自定義tab-->
<!-- 設(shè)置可滑動(dòng)-->
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
//設(shè)置ViewPager
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
//設(shè)置tablayout，viewpager上的標(biāo)題
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setSelectedTabIndicatorColor(getResources().getColor(R.color.colorPrimaryDark));
}
/**
* 設(shè)置item
* @param viewPager
*/
private void setupViewPager(ViewPager viewPager) {
InfoAdapter adapter = new InfoAdapter(getSupportFragmentManager());
adapter.addFragment(new HomeFragment(), "主頁");
adapter.addFragment(new WeiBoFragment(), "微博");
adapter.addFragment(new PhotoFragment(), "相冊(cè)");
viewPager.setAdapter(adapter);
}
/**
* Created by chenlijin on 2015/12/10. 傳入標(biāo)題的FragmentPagerAdapter
*/
public class InfoAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragments = new ArrayList<>();
private final List<String> mFragmentTitles = new ArrayList<>();
public InfoAdapter(FragmentManager fm) {
super(fm);
}
public void addFragment(Fragment fragment, String title) {
mFragments.add(fragment);
mFragmentTitles.add(title);
}
@Override
public Fragment getItem(int position) {
return mFragments.get(position);
}
@Override
public int getCount() {
return mFragments.size();
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitles.get(position);
}
}
Glide加載圖片：
public static void loadToImageView(String url, ImageView imageView) {
if (url.endsWith("gif")) {
loadToImageViewStaticGif(url, imageView);
} else {
Glide.with(BaseApplication.getContext())
.load(url)
.placeholder(R.drawable.loading)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.centerCrop()
.into(imageView);
}
}
Glide下載圖片：
public static void saveImage(String url, final String name) {
Glide.with(BaseApplication.getContext())
.load(url)
.asBitmap()
.override(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
// Do something with bitmap here.
saveBitmap(name,resource);
}
});
}
public static void saveBitmap(String bitName, Bitmap mBitmap) {
File f = new File("/sdcard/Pictures/" + bitName+".png");
try {
f.createNewFile();
} catch (IOException e) {
}
FileOutputStream fOut = null;
try {
fOut = new FileOutputStream(f);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
try {
fOut.flush();
} catch (IOException e) {
e.printStackTrace();
}
try {
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
}
1~9張圖片的加載：
使用recyclerview加載三種不同的布局影暴。
@Override
public int getItemViewType(int position) {
switch (mShopInfoList.get(position).getImageList().size()) {
case 1:
return PIC_ONE;
case 4:
return PIC_FOUR;
default:
return PIC_OTHER;
}
}
share動(dòng)畫：
1错邦，設(shè)置共享元素的標(biāo)簽
android:transitionName="share"
2，通過ActivityOptions型宙，傳入要分享的view和標(biāo)簽名
Intent intent = new Intent(mLayoutInflater.getContext(), OnePicZoomInImageActivity.class);
intent.putParcelableArrayListExtra(Config.IMAGE_URL_LIS T, (ArrayList<? extends Parcelable>) imageList);
// of both activities are defined with android:transitionName="share"
ActivityOptions options = ActivityOptions
.makeSceneTransitionAnimation((Activity) mLayoutInflater.getContext(), imageview, "share");
mLayoutInflater.getContext().startActivity(intent,options.toBundle());
普通activity的切換動(dòng)畫：
mLayoutInflater.getContext().startActivity(intent,
ActivityOptions.makeSceneTransitionAnimation((Activity)mLayoutInflater.getContext()).toBundle());
設(shè)置statusbar為透明色
//設(shè)置statusbar為透明色
private void setStatusBarColor() {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
window.setNavigationBarColor(Color.TRANSPARENT);
}
給imageview添加手勢(shì)操作
PhotoViewAttachermAttacher;
mAttacher = new PhotoViewAttacher(mImageView);
遇到的問題：
viewpager和photoview一起使用崩潰的問題
java.lang.IllegalArgumentException: pointerIndexoutofrange
public class PictureChildViewPager extends ViewPager {
public PictureChildViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
public PictureChildViewPager(Context context) {
super(context);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
try {
return super.onInterceptTouchEvent(ev);
} catch (IllegalArgumentException e) {
e.printStackTrace();
return false;
}
}
@Override
public boolean onTouchEvent(MotionEvent arg0) {
try {
return super.onTouchEvent(arg0);
} catch (IllegalArgumentException ex) {
return false;
}
}
scrollview下嵌套viewpager撬呢，viewpager高度不顯示
// //解決viewpager高度無法顯示問題
// mNestedScrollView.setFillViewport(true);
設(shè)置linearlayout在appbarlayout下
沒有解決的問題
share動(dòng)畫，打開的activity是viewpager返回時(shí)的圖片不對(duì)
glide加載網(wǎng)絡(luò)上的長(zhǎng)圖時(shí)妆兑，寬度設(shè)置為match失效
glide加載圖片時(shí)魂拦，如果設(shè)置圖片為match match圖片會(huì)先顯示在上方再移動(dòng)到中間
