我在我的应用程序的webview中使用谷歌表单,它工作得很好,直到我今天早上看到键盘没有出现用户输入。

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class AndroidMobileAppSampleActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final WebView mainWebView = (WebView) findViewById(R.id.mainWebView);

    WebSettings webSettings = mainWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mainWebView.setWebViewClient(new WebViewClient());
    mainWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

    mainWebView.loadUrl("https://docs.google.com/forms/d/1Q3Ld-JwtrxSAlw-7mcVcEYH4kohCSqhzRZ9SHsRyu_U/viewform?usp=send_form");
    {

mainWebView.setWebViewClient(new WebViewClient() {
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        mainWebView.loadUrl("file:///android_asset/b.txt");

    }
});

class MyCustomWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}
}}} 

这是logcat

2 个答案:

答案 0 :(得分:1)

你用什么级别的api进行测试?

android api 21有bug未解决。这出现在logcat输出中:

W/ActivityManager﹕ getTasks: caller 10077 does not hold GET_TASKS; limiting output

据我所知,当调用以下代码时会出现问题:

ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(5);

我添加版本检查时解决了:

if(Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)

答案 1 :(得分:0)

您只能在AndroidManifest.xml中添加此行

<uses-permission android:name="android.permission.GET_TASKS" />

我希望你能解决这个问题。
