我已经知道如何实现它。受Intent to choose between the camera or the gallery in Android
的启发问题的答案不仅仅是一个意图。简单来说,在我的问题截屏中,有3个动作,即3个Intent。关键方法是Intent.createChooser()
这是我完整的代码:
public void click(View view) {
File file = getExternalFilesDir(Environment.DIRECTORY_DCIM);
Uri cameraOutputUri = Uri.fromFile(file);
Intent intent = getPickIntent(cameraOutputUri);
startActivityForResult(intent, -1);
}
private Intent getPickIntent(Uri cameraOutputUri) {
final List<Intent> intents = new ArrayList<Intent>();
if (true) {
intents.add(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI));
}
if (true) {
setCameraIntents(intents, cameraOutputUri);
}
if (intents.isEmpty()) return null;
Intent result = Intent.createChooser(intents.remove(0), null);
if (!intents.isEmpty()) {
result.putExtra(Intent.EXTRA_INITIAL_INTENTS, intents.toArray(new Parcelable[] {}));
}
return result;
}
private void setCameraIntents(List<Intent> cameraIntents, Uri output) {
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, output);
cameraIntents.add(intent);
}
}
