在文档中如下声明： public abstract class LayoutInflater extends Object 获得 LayoutInflater 实例的三种方式 1.LayoutInflater inflater...LayoutInflater inflater = LayoutInflater.from(context); 其实，这三种方式本质是相同的，从源码中可以看出： getLayoutInflater()：...) public View inflate (int resource, ViewGroup root, boolean attachToRoot) 示意代码： LayoutInflater inflater...= (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE); View view = inflater.inflate(R.layout.custom...注意： ·inflate方法与 findViewById 方法不同； ·inflater 是用来找 res/layout下的 xml 布局文件，并且实例化； ·findViewById() 是找具体 xml
public abstract class LayoutInflater extends Object 使用方式 获得 LayoutInflater 实例的三种方式： LayoutInflater inflater...); LayoutInflater inflater = LayoutInflater.from(context); 三种方法的关系 getLayoutInflater方法是Activity方法，...LayoutInflater LayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE...attachToRoot) public View inflate (int resource, ViewGroup root, boolean attachToRoot) 使用代码： LayoutInflater inflater...= (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE); View view = inflater.inflate(R.layout.custom
基本实现 主要借助的就是Deflater, Inflater两个工具类，其使用姿势如下 public static String uncompress(byte[] input) throws IOException...{ Inflater inflater = new Inflater(); inflater.setInput(input); ByteArrayOutputStream baos...inflater.finished()) { int count = inflater.inflate(buff); baos.write(buff, 0...inflater = new Inflater(nowrap); inflater.setInput(input); ByteArrayOutputStream baos = new...inflater.finished()) { int count = inflater.inflate(buff); baos.write(buff, 0
一、分析问题背景 java.util.zip.DataFormatException异常通常出现在使用Inflater类进行数据解压缩时。Inflater类用于解压缩通过Deflater类压缩的数据。...byte[] compressedData = ...; // 通过某种方式获得的压缩数据 Inflater inflater = new Inflater(); inflater.setInput(compressedData...未完整传递数据：传递给Inflater的数据不完整，可能是数据在传输过程中被截断或丢失。 错误的输入数据：在Inflater中设置了错误的输入数据，导致解压缩失败。...inflater = new Inflater(); inflater.setInput(compressedData); byte[] result = new byte[100];...以下是一个改进后的代码示例： public void decompressData(byte[] compressedData) { Inflater inflater = new Inflater
LayoutInflater inflater = getLayoutInflater();//调用Activity的getLayoutInflater() 2....LayoutInflater inflater = LayoutInflater.from(context); 3....LayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE...public View inflate (int resource, ViewGroup root, boolean attachToRoot) eg: LayoutInflater inflater...(R.layout.list_item, null); inflater.inflate(R.layout.list_item, parent, false); inflater.inflate(R.layout.list_item
获得 LayoutInflater 实例的三种方式: LayoutInflater inflater = getLayoutInflater();//调用Activity的getLayoutInflater...() LayoutInflater inflater = LayoutInflater.from(context); LayoutInflater inflater = (LayoutInflater...)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE); 实战应用 使用实例...LayoutParams.WRAP_CONTENT); lp2.addRule(RelativeLayout.CENTER_IN_PARENT); LayoutInflater inflater...= LayoutInflater.from(this); RelativeLayout rly = (RelativeLayout) inflater.inflate(
onCreateViewLazy(savedInstanceState); } else { LayoutInflater layoutInflater = inflater...onFragmentStopLazy(); } } } protected View getPreviewLayout(LayoutInflater inflater...= null) { layout.removeAllViews(); View view = inflater.inflate(layoutResID,...android.view.ViewGroup; public class BaseFragment extends Fragment { protected LayoutInflater inflater..., ViewGroup container, Bundle savedInstanceState) { this.inflater = inflater; this.container
; if (context instanceof Activity) { inflater = ((Activity) context).getLayoutInflater...(); } else { inflater = LayoutInflater.from(context); } if (inflater...== null) { return null; } if (inflater.getFactory2() == null) {...BackgroundFactory factory = setDelegateFactory(context); inflater.setFactory2(factory);...(inflater.getFactory2() instanceof BackgroundFactory)) { forceSetFactory2(inflater);
private ArrayAdapter adapter; @Nullable @Override public View onCreateView(LayoutInflater inflater..., @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate...container, false); viewPager = (ViewPager) view.findViewById(R.id.indicator_all); inflater...= getLayoutInflater(); view1 = inflater.inflate(R.layout.layout1, null); view2 = inflater.inflate...(R.layout.layout2, null); view3 = inflater.inflate(R.layout.layout3, null); view4 = inflater.inflate
View view, ViewGroup.LayoutParams params) 2.用法 1）setContentView(R.layout.main); 2）LayoutInflater inflater...= (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); View view = (View) inflater.inflate...LayoutInflater inflater = getLayoutInflater(); //调用Activity的getLayoutInflater() 2....LayoutInflater localinflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE...LayoutInflater inflater = LayoutInflater.from(context); 其实，这三种方式本质是相同的，从源码中可以得出结论：这三种方式最终本质是都是调用的
如果 end 方法没有调用，就会导致内存泄漏，java.util.zip.InflaterInputStream 类的 close 方法在一些场景下是不会调用 Inflater.end 方法，如下所示。...但是 Inflater 类有实现 finalize 方法，在 Inflater 对象不可达以后，JVM 会帮忙调用 Inflater 类的 finalize 方法 public class Inflater...Inflater 因为还没被 FinalizerThread 执行 fianlize 方法，导致没有释放 Inflater 的 finalize 方法被调用，但是被 libc 的 ptmalloc 缓存...类没有被回收，经过内存分析看，发现 java.util.zip.Inflater 类有 6k 多没有被回收。...方案 2：修改 FastClasspathScanner 代码，在流关闭的时候，顺带关闭 Inflater, SpringBoot 里面是这么实现的。
LayoutInflater inflater = getLayoutInflater();//调用Activity的getLayoutInflater() 2 2....LayoutInflater inflater = LayoutInflater.from(context); 3 3....LayoutInflater inflater = (LayoutInflater)context.getSystemService 4 (...= (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE); 2 View view = inflater.inflate(R.layout.custom...注意： ·inflate 方法与 findViewById 方法不同； ·inflater 是用来找 res/layout 下的 xml 布局文件，并且实例化； ·findViewById() 是找具体
上代码： 第一种方法 LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE...); 第二种方法 LayoutInflater inflater = LayoutInflater.from(context); 第三种方法 // 在Activity内部调用getLayoutInflater...View view=inflater.inflate(R.layout.ID, null); inflate方法 点击进入sdk源码，可以发现inflate方法有以下几个重载方法： 它们返回的值都是View...示例代码： LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE); View view...= inflater.inflate(R.layout.custom, (ViewGroup)findViewById(R.id.test)); //EditText editText = (EditText

LayoutInflater inflater = getActivity().getLayoutInflater(); View view = inflater.inflate... LayoutInflater inflater = getActivity().getLayoutInflater(); View view = inflater.inflate...

通过这个方法让fragment显示自己的布局 @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater..., @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate...extends Fragment { @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater..., @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate...Required empty public constructor } @Override public View onCreateView(LayoutInflater inflater
= getActivity().getLayoutInflater(); View view = inflater.inflate(R.layout.fragment_dialog, null...= getActivity().getLayoutInflater(); View view = inflater.inflate(R.layout.fragment_dialog, null...return dialog; } 对于方法 ②，和普通的 Fragment 用法基本一致： @Override public View onCreateView(LayoutInflater inflater...= getActivity().getLayoutInflater(); View view = inflater.inflate(R.layout.fragment_dialog, null...= getActivity().getLayoutInflater(); View view = inflater.inflate(R.layout.fragment_dialog, null
以下是使用这种方法来解决上面的报错的示例代码： class MyFragment : Fragment() { override fun onCreateView( inflater...{ return inflater.inflate(R.layout.fragment_layout, container, false) } override fun...以下是使用这种方法来解决上面的报错的示例代码： class MyFragment : Fragment() { override fun onCreateView( inflater...{ return inflater.inflate(R.layout.fragment_layout, container, false) } override fun...{ return inflater.inflate(R.layout.fragment_layout, container, false) } override fun
