java - 在 android 中通过 intents 访问 Google Translate App

Question

我正在开发一个 Android 应用程序，我在其中通过 Intents 调用谷歌翻译应用程序。程序描述 here真的很有帮助，但我不明白为什么我的应用程序崩溃并显示“找不到处理 Intent 的 Activity ”。

提前致谢!

这是我的代码，

public void translate()
{
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_TEXT, "hello");
    intent.putExtra("key_text_input", "hello");
    intent.putExtra("key_text_output", "");
    intent.putExtra("key_language_from", "en");
    intent.putExtra("key_language_to", "mal");
    intent.putExtra("key_suggest_translation", "");
    intent.putExtra("key_from_floating_window", false);
            new ComponentName(
                "com.google.android.apps.translate",
                "com.google.android.apps.translate.HomeActivity");
    startActivity(intent);

}

这就是我的 logcat 显示的内容

您需要将 HomeActivity 更改为 TranslateActivity

try {
   Intent intent = new Intent();
   intent.setAction(Intent.ACTION_SEND);
   intent.putExtra(Intent.EXTRA_TEXT, "hello");
   intent.putExtra("key_text_input", "hello");
   intent.putExtra("key_text_output", "");
   intent.putExtra("key_language_from", "en");
   intent.putExtra("key_language_to", "mal");
   intent.putExtra("key_suggest_translation", "");
   intent.putExtra("key_from_floating_window", false);
   intent.setComponent(new ComponentName(
        "com.google.android.apps.translate",
        //Change is here 
        //"com.google.android.apps.translate.HomeActivity")); 
        "com.google.android.apps.translate.TranslateActivity"));
   startActivity(intent);
} catch (ActivityNotFoundException e) {
    // TODO Auto-generated catch block
    Toast.makeText(getApplication(), "Sorry, No Google Translation Installed",
            Toast.LENGTH_SHORT).show();
}
