我需要像google Play 中的应用程序Photo Warp一样扭曲图像.我在BitMapmesh.java中使用warp 但是,我需要Photo Warp中的其他类型

Warp http://evergreenhits.com/ad/PhotoShare.png

请给我任何建议.

我需要在代码中使用以下xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:orientation="vertical" android:gravity="right"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000"
            >
            <android.webkit.WebView android:layout_width="fill_parent"
            android:id="@+id/adview"
            android:scrollbars="none"
            android:layout_height="50dp"
            android:layout_alignParentLeft="true"
            android:layout_alignParentBottom="true"
            ></android.webkit.WebView>
            <Button android:layout_width="wrap_content" android:text="x" android:textColor="#000000" 
            android:layout_height="wrap_content" android:id="@+id/hide_popup_button" android:background="#00000000" 
            android:layout_alignTop="@+id/adview" android:layout_alignParentRight="true"></Button>

        </RelativeLayout> 

我使用下面的代码,但我得到一个Force close:

RelativeLayout popwindow=new RelativeLayout(this);

        RelativeLayout.LayoutParams rl= new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 50);
        popwindow.setLayoutParams(rl);
        WebView w= new WebView(this);
        w.setId(0X100);
        w.setScrollContainer(false);
        android.widget.RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)w.getLayoutParams();
        params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
        Button b=new Button(this);
        b.setId(0X101);
        b.setText("X");
        b.setBackgroundColor(Color.TRANSPARENT);
        b.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        android.widget.RelativeLayout.LayoutParams paramsbut = (RelativeLayout.LayoutParams)b.getLayoutParams();
        paramsbut.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        paramsbut.addRule(RelativeLayout.ALIGN_TOP,w.getId() );
        popwindow.addView(w,params);
        popwindow.addView(b,paramsbut);
        setContentView(popwindow);

我需要有关如何通过java代码制作xml布局的建议.

我正在使用OCR android.从谷歌搜索获得样本并使用android tesseract.我把项目作为库并引用了另一个项目但是,当我运行项目时,它在Logcat中显示以下内容

我编写了一个处理程序,每隔一段时间调用该方法.我想在destroy()中删除该处理程序.我用的代码如下,In Oncreate()

private final Handler _handler = new Handler();
public int DATA_INTERVAL = 30 * 1000;
Runnable getData;
 getData = new Runnable()
        {
            @Override
            public void run()
            {
                     recieveData();
            }
        };

 _handler.postDelayed(getData, DATA_INTERVAL);

在ondestroy()中,我使用,

_handler.removeCallbacks(getData);

但removecallbacks不起作用.它在退出活动后调用.
