Question

我想将数据发送到另一个特定应用。以下内容将String发送到指定的应用程序。

如何向应用发送3个字符串？我是否必须将它们放入数组或使用HashMap？

Intent sendIntent = new Intent();
    sendIntent.setClassName("com.example.application",
            "com.example.application.MainActivity");
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "String1");
    sendIntent.setType("text/plain");
    startActivity(sendIntent);

Answer 1

您可以使用更多putExtra＆只需使用其他名称！

Intent sendIntent = new Intent();
sendIntent.setClassName("com.example.application",
        "com.example.application.MainActivity");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra("First", "String1");
sendIntent.putExtra("Second", "String2");
sendIntent.putExtra("Third", "String3");
sendIntent.setType("text/plain");
startActivity(sendIntent);

获得字符串：

String first = null;
String second = null;
String third = null;

if (savedInstanceState == null) {
    Bundle extras = getIntent().getExtras();
    if(extras != null) {
        first = extras.getString("First");
        second= extras.getString("Second");
        third = extras.getString("Third");
    }
}

在发件人应用

中

String[] myStrings = new String[] {"string1", "string2","string3"};
intent.putExtra("strings", myStrings);

在接收器应用

中

String[] myStrings = intent.getStringArrayExtra("strings");

从here获得。

Answer 3

Intent sendIntent = new Intent();
    sendIntent.setClassName("com.example.application",
            "com.example.application.MainActivity");
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra("StringOne", "StringValue1");
    sendIntent.putExtra("StringThree", "StringValue3");
    sendIntent.putExtra("StringTwo", "StringValue3");
    sendIntent.setType("text/plain");
    startActivity(sendIntent);

收到的活动

getIntent().getStringExtra(StringOne);
getIntent().getStringExtra(StringThree);
getIntent().getStringExtra(StringTwo);
