Question

我想在我的Android应用中添加“分享”按钮。

喜欢那个

我添加了“分享”按钮，但按钮未激活。我点击了，但没有任何反应。

我在MainActivity.java中的代码：

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"));
}

我想在第一个标签（first_tab.xml）或第二个标签（second_tab.xml）中分享文字。

选项卡（xml）中的代码（如果需要）：

<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" />

Answer 1

添加Button，然后点击Button添加此代码：

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"));

有用的链接：

For basic sharing

For customization

创建一个包含id共享的按钮，并添加以下代码段。

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"));
    }
});

以上代码段将在共享按钮点击操作上打开共享选择器。但请注意......共享代码段可能无法使用模拟器输出非常好的结果。对于实际结果，请在Android设备上运行代码段以获得真实结果。

在科特林：

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 :"))

Doctor found issues in 1 category. 的文件夹，并创建一个名为 xml的新XML资源文件。 em>并将以下代码放入其中：

res

现在转到 provider_paths.xml 文件夹并打开 <?xml version="1.0" encoding="utf-8"?> <paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="files" path="."/> <external-path name="external_files" path="."/> </paths> ，然后将以下代码放入manifests标记内：

AndroidManifest.xml

现在您将以下代码放入<application>中：

<provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.provider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" /> // provider_paths.xml file path in this example </provider>
