本文主要介绍Android实现拍照、录像、录音代码的资料,这里整理了详细的代码,有需要的小伙伴可以参考下。

RecordActivity.java

import android.widget.*;
public class RecordActivity extends Activity implements onClickListener {
    private static final int RESULT_CAPTURE_IMAGE = 1;// 照相的requestCode
    private static final int REQUEST_CODE_TAKE_VIDEO = 2;// 摄像的照相的requestCode
    private static final int RESULT_CAPTURE_RECORDER_SOUND = 3;// 录音的requestCode
    private String strImgPath = "";// 照片文件绝对路径
    private String strVideoPath = "";// 视频文件的绝对路径
    private String strRecorderPath = "";// 录音文件的绝对路径
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 this.setContentView(R.layout.problem_report);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  Toast.makeText(this, strImgPath, Toast.LENGTH_SHORT).show();
     }
     break;

     if (resultCode == RESULT_OK) {

    }

 String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + ".jpg";//照片命名
 File out = new File(strImgPath);
 if (!out.exists()) {
     out.mkdirs();
 }
 out = new File(strImgPath, fileName);
 strImgPath = strImgPath + fileName;//该照片的绝对路径
 Uri uri = Uri.fromFile(out);
 imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
 imageCaptureIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
 startActivityForResult(imageCaptureIntent, RESULT_CAPTURE_IMAGE);
 
    }
    
    private void videoMethod() {
 Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
 intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
 startActivityForResult(intent, REQUEST_CODE_TAKE_VIDEO);
    }
    
    private void soundRecorderMethod() {

    }
 
    
    private void showToast(String text, int duration) {
 Toast.makeText(ProblemReport.this, text, duration).show();
    }
}
