Question

因此，我开发了一个活动，在单个TextView中显示来自外部文件（quotes.txt）的随机引号。它工作正常。现在，我要做的是在屏幕上显示这个随机引用并通过短信，蓝牙，脸书，whatsapp等分享......

我实现了共享Intent。但它不起作用。事实上，有一些错误。我是新手。这是我的代码

MainActivity.java

public boolean onCreateOptionsMenu (Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);

    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setAction(android.content.Intent.ACTION_SEND);

    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_TEXT, Quotes.add(line));
    startActivity(Intent.createChooser(shareIntent, "Share"));




    return true;
}



}

菜单Main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/action_share"
    android:orderInCategory="100"
    android:showAsAction="ifRoom"
    android:title="Share"
    android:actionProviderClass="android.widget.ShareActionProvider"/>

尝试以下代码

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setAction(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, ""); //<=adding blank quotes
shareIntent.putExtra(Intent.EXTRA_TEXT, Quotes.add(line));    
startActivity(Intent.createChooser(shareIntent, "Share"));

修改

您需要在TextView 活动
中的课程级别定义Main
TextView textView ; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //defining view at class level, make it accessible in all method //initalize the view in onCreate() instead of updateTextView() textView = (TextView)findViewById(R.id.widget_textview1); } public boolean onCreateOptionsMenu (Menu menu) { Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); shareIntent.setAction(android.content.Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, ""); //<=adding blank quotes shareIntent.putExtra(Intent.EXTRA_TEXT, textView.getText().toString()); startActivity(Intent.createChooser(shareIntent, "Share")); }

在updateTextView()方法中，执行此操作

private void updateTextView() { List<String> Quotes = getListFromTxtFile("quotes.txt"); int nextInt = random.nextInt(Quotes.size()); textView.setText(Quotes.get(nextInt)); }
