我尝试使用onActivityResult来启动Android图库,以便根据所选的ImageButton显示照片或视频。
问题是当试图打开照片时,它试图启动视频播放器并且我不确定原因。
P.S。
可以使用视频ImageButton成功播放视频。
private static final int SELECT_PHOTO = 1;
private static final int SELECT_VIDEO = 1;
ImageButton pb = (ImageButton) findViewById(R.id.photos);
pb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(intent, SELECT_PHOTO);
}
});
ImageButton vb = (ImageButton) findViewById(R.id.video);
vb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intentGallery = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intentGallery.setType("video/*");
startActivityForResult(intentGallery, 1);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_VIDEO) {
{
Uri selectedVideo = data.getData();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedVideo, "video/*");
startActivity(intent);
}
} else if (requestCode == SELECT_PHOTO) {
Uri selectedImage = data.getData();
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(selectedImage, "image/*");
startActivity(intent);
}
答案 0 :(得分:0)
private static final int SELECT_PHOTO = 1;
private static final int SELECT_VIDEO = 1;
他们需要有所不同,有价值" 1"意味着他们进入同一个"如果" onActivityResult()
。
此外,它只播放视频,因为这是你的第一个"如果" onActivityResult()
内的条件,总是最终成为:
startActivityForResult(intentGallery, 1);
startActivityForResult(intent, SELECT_PHOTO);
比较它们时正确传递两者。试试吧:
private static final int SELECT_PHOTO = 1;
private static final int SELECT_VIDEO = 2;
startActivityForResult(intentGallery, SELECT_VIDEO);
startActivityForResult(intent, SELECT_PHOTO);

SLECT_VIDEO和SELECT_PHOTO不能相同....
