4. it.setDataAndType(uri, "audio/mp3");
5. startActivity(it);

2. Intent it = new Intent(Intent.ACTION_VIEW, uri);

进入联系人界面

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(People.CONTENT_URI);
startActivity(intent);

查看某个联系人，当然这里是ACTION_VIEW，如果为选择并返回action改为ACTION_PICK，当然处理intent时返回需要用到startActivityforResult

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最后的ID参数为联系人Provider中的数据库BaseID，即哪一行
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(personUri);
startActivity(intent);

选择一个图片

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, 0);

调用Android设备的照相机，并设置拍照后存放位置

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment
.getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置为sdcard卡上cwj文件夹，文件名为android123.jpg格式
startActivityForResult(intent, 0);

自定义的Activity调用

Intent intent = new Intent();
intent.setClass(dataactivity.this, test3.class);
startActivity(intent);
要注意包的声明和权限修改，即AndroidManifest.xml的修改！
