Android 调用系统的方法总结

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");//保存到指定目录File file = new File("/mnt/sdcard/picture");if (!file.exists()) {  file.mkdirs();}File out = new File("/mnt/sdcard/picture/123.jpg");Uri uri = Uri.fromFile(out);intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);startActivityForResult(intent, 0);

Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);startActivityForResult(intent, 1);

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0.5);//画质0.5intent.putExtra(android.provider.MediaStore.EXTRA_SIZE_LIMIT,768000);intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 70000);//70sFile file = new File("/mnt/sdcard/video");if (!file.exists()) {   file.mkdirs();}File tmpFile = new File("/mnt/sdcard/video/123.mp4");Uri outputFileUri = Uri.fromFile(tmpFile);// 设置视频的品质为高mIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);// 设置视频文件名mIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);startActivityForResult(mIntent, 2);

Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i, RESULT_LOAD_IMAGE);

Intent intent = new Intent();intent.setType("image/*");intent.setAction(Intent.ACTION_GET_CONTENT);startActivityForResult(intent, PIC);
