这是我的应用程序的导航:

Activity1来电Activity2→ Activity2.finish(),拨打Activity3→Activity3.finish()

当Activity3完成后,它调用onResume的方法Activity1.现在我如何将值传递Activity3给Activity1？

我如何在android中解码utf-8字符串？我已尝试使用此命令但输出相同的输入:

URLDecoder.decode("hello&//à", "UTF-8");

new String("hello&//à", "UTF-8");

EntityUtils.toString("hello&//à", "utf-8");

根据标题,我如何在webview中隐藏缩放控件？

如何使用Android的MapView对象在Google地图中添加搜索栏？

    public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mapmain);


    mapView = (MapView) findViewById(R.id.mapView);
    LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
        new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

}
