intent用法收集

1. 從AP開啟控制台location的設定

startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));

2.從AP開啟android內部圖庫，並傳回選擇的圖片

startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), SELECT_IMAGE);

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (requestCode == SELECT_IMAGE)
        if (resultCode == Activity.RESULT_OK) {
          Uri selectedImage = data.getData();
          // TODO Do something with the select image URI
        } 
    }

3. 切換到另外一個class視窗

Intent intent = new Intent(this, RedirectGetter.class);
startActivityForResult(intent, INIT_TEXT_REQUEST);
