拍照并显示以及获取路径后上传

简单的 Android 拍照并显示以及获取路径后上传

Activity 中的代码，我只贴出重要的事件部分代码

public void doPhoto(View view)

{

destoryBimap();

String state = Environment.getExternalStorageState();

if (state.equals(Environment.MEDIA_MOUNTED)) {

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

startActivityForResult(intent, 1);

} else {

Toast.makeText(MainActivity.this, "没有SD卡", Toast.LENGTH_LONG).show();

}

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data)

{

Uri uri = data.getData();

if (uri != null) {

this.photo = BitmapFactory.decodeFile(uri.getPath());

}

if (this.photo == null) {

Bundle bundle = data.getExtras();

if (bundle != null) {

this.photo = (Bitmap) bundle.get("data");

} else {

Toast.makeText(MainActivity.this, "拍照失败", Toast.LENGTH_LONG).show();

return;

}

}

FileOutputStream fileOutputStream = null;

try {

// 获取 SD 卡根目录

String saveDir = Environment.getExternalStorageDirectory() + "/meitian_photos";

// 新建目录

File dir = new File(saveDir);

if (! dir.exists()) dir.mkdir();

// 生成文件名

SimpleDateFormat t = new SimpleDateFormat("yyyyMMddssSSS");

String filename = "MT" + (t.format(new Date())) + ".jpg";

// 新建文件

File file = new File(saveDir, filename);

// 打开文件输出流

fileOutputStream = new FileOutputStream(file);

// 生成图片文件

this.photo.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);

// 相片的完整路径

this.picPath = file.getPath();

ImageView imageView = (ImageView) findViewById(R.id.showPhoto);

imageView.setImageBitmap(this.photo);

} catch (Exception e) {

e.printStackTrace();

} finally {

if (fileOutputStream != null) {

try {

fileOutputStream.close();

} catch (Exception e) {

e.printStackTrace();

}

}

}

}

/**

* 销毁图片文件

*/

private void destoryBimap()

{

if (photo != null && ! photo.isRecycled()) {

photo.recycle();

photo = null;

}

}
