怎么解决安卓5.1.1 webview 不支持<input type="file" ⼀&gt

android里webview不支持input type=file的解决方法

1. activity定义

2. public ValueCallback mUploadMessage;

3. public final static int FILECHOOSER_RESULTCODE = 1;

2.扩展WebChromeClient

WebChromeClient chromeClient = new WebChromeClientImpl();

view.setWebChromeClient(chromeClient);

3.实现WebChromeClientImpl类

private class WebChromeClientImpl extends WebChromeClient{

//扩展支持alert事件

@Override

public boolean onJsAlert(WebView view, String url, String message,JsResult result) {

Builder builder = new Builder(view.getContext());

builder.setTitle("商机通提示").setMessage(message).setPositiveButton("确定", null);

builder.setCancelable(false);

builder.setIcon(R.drawable.ic_launcher);

AlertDialog dialog = builder.create();

dialog.show();

result.confirm();

return true;

}

//扩展浏览器上传文件

//3.0++版本

public void openFileChooser(ValueCallback uploadMsg, String acceptType) {

mUploadMessage = uploadMsg;

Intent i = new Intent(Intent.ACTION_GET_CONTENT);

i.addCategory(Intent.CATEGORY_OPENABLE);

i.setType("*/*");

activity.startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);

}

//3.0--版本

public void openFileChooser(ValueCallback uploadMsg) {

mUploadMessage = uploadMsg;

Intent i = new Intent(Intent.ACTION_GET_CONTENT);

i.addCategory(Intent.CATEGORY_OPENABLE);

i.setType("*/*");

activity.startActivityForResult(Intent.createChooser(i, "file Browser"),FILECHOOSER_RESULTCODE);

}

}
