通过Android中的意图访问谷歌翻译应用程序

Question

我正在开发一个Android应用程序,我通过Intents调用Google Translate应用程序.这里描述的过程非常有用,但我无法弄清楚为什么我的应用程序崩溃说"没有找到活动来处理Intent".

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

你需要HomeActivity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();
}
