android启动相机,android – 如何启动相机并拍照

在我的应用程序中,我使用以下代码启动相机：

public void imageFromCamera() {

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

mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",

"PIC"+System.currentTimeMillis()+".jpg");

mSelectedImagePath = mImageFile.getAbsolutePath();

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));

startActivityForResult(intent, TAKE_PICTURE);

}

这会将图像保存到路径mSelectedImagePath,即/sdcard/MyApp/.jpg.

然后在onActivityResult中捕获IMAGE_CAPTURE意图的返回并启动您的活动以从那里编辑图像！

public void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

if (resultCode == RESULT_OK) {

switch(requestCode) {

case TAKE_PICTURE:

//Launch ImageEdit Activity

Intent i = new Intent(this, ImageEdit.class);

i.putString("imgPath", "mSelectedImagePath");

startActivity(i);

break;

}

}

}

希望这可以帮助！
