Andriod webview实现文件上传

Andriod 到3.2版本为止，webview方式下使用点击后都没有反应。实际上顶层是有隐含的接口没实现的，可以自己重写这个方法来实现。以phonegap为例：

public class App extends DroidGap {
    private ValueCallback<Uri> mUploadMessage;
    private final static int FILECHOOSER_RESULTCODE = 1;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.init();
        // WebView wv = new WebView(this);
        // wv.setWebViewClient(new WebViewClient());
        this.appView.setWebChromeClient(new CordovaChromeClient(App.this) {
            // For Android 3.0+
            public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("image/*");
                App.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
            }

            // The undocumented magic method override
            // Eclipse will swear at you if you try to put @Override here
            public void openFileChooser(ValueCallback<Uri> uploadMsg) {
                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("image/*");
                App.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), App.FILECHOOSER_RESULTCODE);
            }
        });

        // setContentView(wv);
        super.loadUrl("file:///android_asset/www/login.html");
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        if (requestCode == FILECHOOSER_RESULTCODE) {
            if (null == mUploadMessage)
                return;
            Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData();
            mUploadMessage.onReceiveValue(result);
            mUploadMessage = null;
        }
    }
}

如果直接的webview方式，extends WebChromeClient即可。参考：http://stackoverflow.com/questions/5907369/file-upload-in-webview
