Question

如何向我的Android应用添加分享按钮，我在这里尝试了几种解决方案，似乎没有任何效果。

activity_main.xml中

感谢您的回答，我尝试了不同的解决方案并且有效。 youtube.com/watch?v=U39RsxrWhIA

Answer 1

在我看来，toll_bar.xml是不必要的。

首先，在activity_main.xml，请更改

<include
    android:id="@+id/toolbar"
    layout="@layout/toll_bar" />

到

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?android:actionBarSize"
    android:background="@color/colorPrimary"/>

第二次，创建一个名为toolbar.xml的菜单文件，将其放入res/menu目录。

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/menu_about"
        android:enabled="true"
        android:icon="@drawable/icon"
        android:title="about"
        app:showAsAction="always" />
    <item
        android:id="@+id/menu_share"
        android:enabled="true"
        android:icon="@drawable/share"
        android:title="share"
        app:showAsAction="always" />
    <item
        android:id="@+id/menu_rate"
        android:enabled="true"
        android:icon="@drawable/rate"
        android:title="rate us"
        app:showAsAction="always" />
</menu>

第三次，这是新的MainActivity.java

public class MainActivity extends AppCompatActivity {

    Toolbar toolbar;


    @Override
    public void onBackPressed() {
        if (mWebView.canGoBack()) {
            mWebView.goBack();
        } else {
            super.onBackPressed();
        }
    }

    private WebView mWebView;

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

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mWebView = (WebView) findViewById(R.id.activity_main_webview);
        mWebView.loadUrl("http://beta.html5test.com/");
        mWebView.loadUrl("file:///android_asset/Html36289/index.html");
        // Force links and redirects to open in the WebView instead of in a browser
        mWebView.setWebViewClient(new WebViewClient());
        // Stop local links and redirects from opening in browser instead of WebView
        mWebView.setWebViewClient(new MyAppWebViewClient());

        mWebView.getSettings().setJavaScriptEnabled(true);
    }

    private boolean isActivityStarted(Intent aIntent) {
        try {
            startActivity(aIntent);
            return true;
        } catch (ActivityNotFoundException e) {
            return false;
        }
    }

    public void onClickRateThisApp() {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse("market://details?id=com.supercell.hayday"));
        if (!isActivityStarted(intent)) {
            intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.package.name"));
            if (!isActivityStarted(intent)) {
                Toast.makeText(this, "Could not open Android market, please check if the market app installed or not. Try again later", Toast.LENGTH_SHORT).show();
            }
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.toolbar, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.menu_about:
                //click the about button
                break;
            case R.id.menu_share:
                //click the share button
                break;
            case R.id.menu_rate:
                onClickRateThisApp();// param view is unnecessary
                break;
        }
        return true;
    }
}

我希望这会对你有所帮助。如果是的话，请采纳我的答案.-D祝你有愉快的一天。

Answer 2

您可以添加此代码，这对您有帮助。

$sql = "SELECT text,pic 
        FROM newstable 
        where type='在线报修上广告' 
        order by id desc limit 0,1";

这将打开app的多重共享选项。这有助于我与另一个人分享。
