对于 Android Studio，如何在 Kotlin 中使用 FAB 将用户发送到搜索页面？

Question

谁能帮我写这段代码？

p0.btnPlay.setOnClickListener {

    val songName = song.songName
    val songArtist = song.songArtist

    Toast.makeText(mCtx, "You clicked this button!", Toast.LENGTH_SHORT).show()

    val webIntent = Intent(Intent.ACTION_WEB_SEARCH, Uri.parse("https://www.youtube.com/results?search_query=$songArtist+$songName"))
    startActivity(webIntent)
}

I am getting an error at startActivity(webIntent) : Type mismatch: inferred type is Intent but Context was expected

如何将用户引导至这样的 YouTube 页面？ toast 消息工作正常，所以按钮点击连接到 XML。

Answer 1

Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, "https://www.youtube.com/results?search_query=$songArtist+$songName");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intent);

Answer 2

如果您的 mCtx 是 Activity context，则使用

try {
    val webIntent = Intent(Intent.ACTION_VIEW, Uri.parse("https://www.youtube.com/results?search_query=$songArtist+$songName"))
    mCtx.startActivity(webIntent)
} catch(ex: Exception) {
    ex.stackTrace
}

如果您在 fragment 中，请尝试使用

try {
    val webIntent = Intent(Intent.ACTION_VIEW, Uri.parse("https://www.youtube.com/results?search_query=$songArtist+$songName"))
    activity!!.startActivity(webIntent)
} catch(ex: Exception) {
    ex.stackTrace
}
