自定义了一个WebView和WebChromeClient,需要在自定义的WebChromeClient内重写onProgressChanged方法,把使用自定义View的类界面中的ProgressBar传递进去,这样该怎么整呢?下面是三个类:
1.自定义WebChromeClient:
public class ZpWebChromeClient extends WebChromeClient {
private OpenFileChooserCallBack mOpenFileChooserCallBack;
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
openFileChooser(uploadMsg, "");
}
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
if (mOpenFileChooserCallBack != null) {
mOpenFileChooserCallBack.openFileChooserCallBack(uploadMsg, acceptType);
}
}
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
openFileChooser(uploadMsg, acceptType);
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {
if (mOpenFileChooserCallBack != null) {
mOpenFileChooserCallBack.showFileChooserCallBack(filePathCallback, fileChooserParams);
}
return true;
}
public void setOpenFileChooserCallBack(OpenFileChooserCallBack callBack) {
mOpenFileChooserCallBack = callBack;
}
public interface OpenFileChooserCallBack {
void openFileChooserCallBack(ValueCallback<Uri> uploadMsg, String acceptType);
void showFileChooserCallBack(ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams);
}
@Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
// if (newProgress == 100) {
// progressBar.setVisibility(View.GONE);//todo:需要把progressbar传进来,加载完网页进度条消失
// } else {
// progressBar.setVisibility(View.VISIBLE);//开始加载网页时显示进度条
// progressBar.setProgress(newProgress);//设置进度值
// }
}
}
2.自定义WebView:
public class ZpWebView extends WebView {
private ZpWebChromeClient webChromeClient;
public ZpWebView(Context context) {
super(context);
initWebView();
}
public ZpWebView(Context context, AttributeSet attrs) {
super(context, attrs);
initWebView();
}
public ZpWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initWebView();
}
private void initWebView() {
webChromeClient = new ZpWebChromeClient();
setWebChromeClient(webChromeClient);
WebSettings webviewSettings = getSettings();
// 不支持缩放
webviewSettings.setSupportZoom(false);
// 自适应屏幕大小
webviewSettings.setUseWideViewPort(true);
webviewSettings.setLoadWithOverviewMode(true);
String cacheDirPath = getContext().getFilesDir().getAbsolutePath() + "cache/";
webviewSettings.setAppCachePath(cacheDirPath);
webviewSettings.setAppCacheEnabled(true);
webviewSettings.setDomStorageEnabled(true);
webviewSettings.setAllowFileAccess(true);
webviewSettings.setAppCacheMaxSize(1024 * 1024 * 8);
webviewSettings.setJavaScriptEnabled(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
webviewSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}
}
public void setOpenFileChooserCallBack(ZpWebChromeClient.OpenFileChooserCallBack callBack) {
webChromeClient.setOpenFileChooserCallBack(callBack);
}
}
3.使用到的类部分代码:
public class WebViewActivity extends BaseActivity {
@BindView(R.id.wv_zp)
ZpWebView mWebView;
@BindView(R.id.pb_web_view)
ProgressBar progressBar; //需要传递的ProgressBar
@BindView(R.id.fl_root_web_view)
FrameLayout mRootView;
private static final int REQUEST_FILE_CAMERA_CODE = 102;
private final static int VIDEO_REQUEST = 120;
// 默认图片压缩大小(单位:K)
public static final int IMAGE_COMPRESS_SIZE_DEFAULT = 400;
// 压缩图片最小高度
public static final int COMPRESS_MIN_HEIGHT = 900;
// 压缩图片最小宽度
public static final int COMPRESS_MIN_WIDTH = 675;
private ValueCallback<Uri> mUploadMsg;
private ValueCallback<Uri[]> mUploadMsgs;
// 相机拍照返回的图片文件
private File mFileFromCamera;
private static final String TAG = "WebViewActivity";
public static void open(Context context, String url, String title) {
Intent intent = new Intent(context, WebViewActivity.class);
intent.putExtra("url", url);
intent.putExtra("title", title);
context.startActivity(intent);
}
@Override
protected int getLayout() {
return R.layout.activity_web_view;
}
@Override
protected void initView(Bundle savedInstanceState) {
String title = getIntent().getStringExtra("title");
mTvTitle.setText(title);
}
....省略了一片代码
在那个自定义Client里面定义一个成员变量process,之后复写set/get方法,你webview就可以调用client对象的set方法,就可以把process传进去了啊
