本文介绍了一个简单的Android应用程序，该程序实现了通过按钮触发相机进行拍照和录像的功能，并使用了MediaStore.ACTION_IMAGE_CAPTURE和MediaStore.ACTION_VIDEO_CAPTURE Intent来启动相机。

package com.example.test111;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void Photo(View v){
        Intent intent = new Intent();
        intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis()+"photo.jpg")));
        startActivityForResult(intent, 10);
    }
    public void Video(View v){
        Intent intent = new Intent();
        intent.setAction(MediaStore.ACTION_VIDEO_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis()+"video.3gp")));
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent, 20);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        if(resultCode==10){
            Toast.makeText(this, "拍照成功", 0).show();
        }
        else if(requestCode == 20){
            Toast.makeText(this, "摄像成功", 0).show();
        }
    }
}
