How to activate “Share” button in android app?

问题

i want to add \"Share\" button to my android app.

Like that

I added \"Share\" button, but button is not active. I click, but nothing happens.

My code in MainActivity.java:

private ShareActionProvider mShareActionProvider;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.share_menu, menu);
    getMenuInflater().inflate(R.menu.main, menu);
    MenuItem item = menu.findItem(R.id.share_menu);
    mShareActionProvider = (ShareActionProvider) menu.findItem(R.id.share_menu).getActionProvider();
    mShareActionProvider.setShareIntent(getDefaultShareIntent());

    return true;
}

{
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.setType(\"text/plain\");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, \"Text\");
    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, \"Subject\");
    startActivity(Intent.createChooser(sharingIntent, \"Share using\"));
}

I want to share text in my first tab (first_tab.xml) or second tab (second_tab.xml).

Code in tab (xml) (If need):

<RelativeLayout 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:background=\"@color/background_color\"
android:paddingBottom=\"@dimen/activity_vertical_margin\"
android:paddingLeft=\"@dimen/activity_horizontal_margin\"
android:paddingRight=\"@dimen/activity_horizontal_margin\"
android:paddingTop=\"@dimen/activity_vertical_margin\"
tools:context=\".MainActivity$DummySectionFragment\" >

<TextView
    android:id=\"@+id/section_label1\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
    android:layout_centerHorizontal=\"true\"
    android:layout_centerVertical=\"true\"
    android:text=\"@string/text\"
    android:textColor=\"@color/text_color\" />

<ImageView
    android:id=\"@+id/imageView1\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
    android:layout_alignParentBottom=\"true\"
    android:layout_centerHorizontal=\"true\"
    android:src=\"@drawable/sprite\" />

回答1:

Add a Button and on click of the Button add this code:

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
sharingIntent.setType("text/plain");
String shareBody = "Here is the share content body";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));

Create a button with an id share and add the following code snippet.

share.setOnClickListener(new View.OnClickListener() {             
    @Override
    public void onClick(View v) {

        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        String shareBody = "Your body here";
        String shareSub = "Your subject here";
        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, shareSub);
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
        startActivity(Intent.createChooser(sharingIntent, "Share using"));
    }
});

The above code snippet will open the share chooser on share button click action. However, note...The share code snippet might not output very good results using emulator. For actual results, run the code snippet on android device to get the real results.

in kotlin :

val sharingIntent = Intent(android.content.Intent.ACTION_SEND)
sharingIntent.type = "text/plain"
val shareBody = "Application Link : https://play.google.com/store/apps/details?id=${App.context.getPackageName()}"
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "App link")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody)
startActivity(Intent.createChooser(sharingIntent, "Share App Link Via :"))
