Question

我想通过点击屏幕在用户onClickListener时获得点击事件。我的布局如下：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/layout_content">

    <WebView
        android:id="@+id/webview_item"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

我试图通过布局Relative setOnClickListener：

来做到这一点

RelativeLayout layoutContent = (RelativeLayout) findViewById(R.id.layout_content);
layoutContent.setOnClickListenner(new OnClickListener() {
    @Override
    public void onClick(View v) {
        ......
    }
});

我可以获得良好的点击事件，直到webview完成加载，我再也无法获得clicklistener了。那么有人建议我在加载webview后能够获得onClicklistener吗？

根据this回答，

WebView似乎没有将点击事件发送到OnClickListener

为此，您需要实施onTouchListener事件。

public class WebViewClicker extends Activity implements OnTouchListener, Handler.Callback {

private static final int CLICK_ON_WEBVIEW = 1;
private static final int CLICK_ON_URL = 2;

private final Handler handler = new Handler(this);

private WebView webView;
private WebViewClient client;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.web_view_clicker);

    webView = (WebView)findViewById(R.id.web);
    webView.setOnTouchListener(this);

    client = new WebViewClient(){ 
        @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { 
            handler.sendEmptyMessage(CLICK_ON_URL);
            return false;
        } 
    }; 

    webView.setWebViewClient(client);
    webView.setVerticalScrollBarEnabled(false);
    webView.loadUrl("http://www.example.com");
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if (v.getId() == R.id.web && event.getAction() == MotionEvent.ACTION_DOWN){
        handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 500);
    }
    return false;
}

@Override
public boolean handleMessage(Message msg) {
    if (msg.what == CLICK_ON_URL){
        handler.removeMessages(CLICK_ON_WEBVIEW);
        return true;
    }
    if (msg.what == CLICK_ON_WEBVIEW){
        Toast.makeText(this, "WebView clicked", Toast.LENGTH_SHORT).show();
        return true;
    }
    return false;
}
}

webView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                Intent intent;
                ActivityModel activityModel = new ActivityModel();
                activityModel.setServerId(activityId);
                if (action.equals("discussion")) {
                    intent = new Intent(BannerPopUp.this, DiscussionActivity.class);
                    intent.putExtra("activityModel", activityModel);
                } else {
                    intent = new Intent(BannerPopUp.this, DisplayActivity.class);
                    intent.putExtra(Constants.MODEL_ACTIVITY, activityModel);
                    if (action.equals("join")) {
                        intent.putExtra(Constants.ACTION, "join");
                    }
                }
                if (!isAppRunning) {
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                }
                startActivity(intent);
                finish();
                return false;`
            }
        });

OnClickListener用于屏幕布局webview
