Android的webview：它不起作用

Question

我不知道我的问题在哪里。
第一个XML：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
android:background="#000" 
tools:context=".Reg"> 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:textAppearance="?android:attr/textAppearanceMedium" 
    android:textColor="#FFFFFF" 
    android:padding="5dp"/> 

<WebView 
    android:id="@+id/webView1" 
    android:layout_width="match_parent" 
    android:layout_height="66dp" 
    /> 

</LinearLayout> 

二：JAVA

WebView mwv; 
mwv = (WebView) findViewById(R.id.webView1); 
mwv.getSettings().setJavaScriptEnabled(true); 
mwv.loadUrl("somepage"); 

页面打开不错，但我无法点击按钮或选择文本框...我只能做到这一点与标签在我的键盘。

任何想法？

请尝试从这，我认为它会帮助你。

public class WebViewActivity extends Activity { 
private WebView webview; 
private static final String TAG = "Main"; 
private ProgressDialog progressBar; 
private TextView header_maintext; 
private TextView headeroptiontext; 
private RelativeLayout back; 
private String url_string="http://www.google.com"; 
private String header_maintext_string="tittle"; 

/** Called when the activity is first created. */ 
@SuppressLint("SetJavaScriptEnabled") @Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.webview_layout); 


    url_string = getIntent().getStringExtra("url"); 
    header_maintext_string = getIntent().getStringExtra("header_text"); 

    webview = (WebView)findViewById(R.id.webview01); 
    header_maintext= (TextView)findViewById(R.id.header_maintext); 
    header_maintext.setText(header_maintext_string); 

    headeroptiontext = (TextView)findViewById(R.id.headeroptiontext); 
    headeroptiontext.setVisibility(View.GONE); 

    WebSettings settings = webview.getSettings(); 
    settings.setJavaScriptEnabled(true); 
    webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY); 
    webview.getSettings().setLoadWithOverviewMode(true); 
    webview.getSettings().setUseWideViewPort(true); 

     back = (RelativeLayout) findViewById(R.id.back_layout); 
     back.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View arg0) 
     { 
      // TODO Auto-generated method stub 
      if(webview.canGoBack() == true) 
       { 
        webview.goBack(); 
       } 
      else 
       { 
        finish(); 
       } 
     } 
    }); 

    final AlertDialog alertDialog = new AlertDialog.Builder(this).create(); 

    progressBar = ProgressDialog.show(WebViewActivity.this, "tittle", "Loading..."); 

    webview.setWebViewClient(new WebViewClient() { 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 

      view.loadUrl(url); 
      return true; 
     } 

     public void onPageFinished(WebView view, String url) { 
      Log.i(TAG, "Finished loading URL: " +url); 
      if (progressBar.isShowing()) { 
       progressBar.dismiss(); 
      } 
     } 

     public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 

      Toast.makeText(WebViewActivity.this, "Oh no! " + description, Toast.LENGTH_SHORT).show(); 
      alertDialog.setTitle("Error"); 
      alertDialog.setMessage(description); 
      alertDialog.setButton("OK", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int which) { 
        return; 
       } 
      }); 
      alertDialog.show(); 
     } 
    }); 
    webview.loadUrl(url_string); 


} 
@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if(event.getAction() == KeyEvent.ACTION_DOWN){ 
     switch(keyCode) 
     { 
     case KeyEvent.KEYCODE_BACK: 
      if(webview.canGoBack() == true){ 
       webview.goBack(); 
      }else{ 
       finish(); 
      } 
      return true; 
     } 

    } 
    return super.onKeyDown(keyCode, event); 
} 
} 

Answer 2

// In this example I didn't place buttons, you need to add dose to your linearlayout and then set the onclicklistener 

WebView webB; 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.browser); 


     webB = (WebView) findViewById(R.id.webView1); 
     webB.setWebViewClient(new browserClient()); //new class so it opens links in the same Activity 
     webB.loadUrl("http://www.google.com"); 

} 


    // the new class 


    import android.webkit.WebView; 
    import android.webkit.WebViewClient; 


    public class browserClient extends WebViewClient { 

     @Override 
     public boolean shouldOverrideUrlLoading(WebView v, String url){ 
     v.loadUrl(url); 
     return true; 
     } 

    }
