我正在开发安卓应用程序。目的是在单击捕获按钮后捕获 5 张图像。我可以使用以下代码捕获单个图像。但是如何在单击一个按钮后拍摄 5 张图像。请问有人可以帮我这样做吗?
代码片段:
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import com.camera.facedetectionexample.R;
public class FaceDetectionExample extends Activity {
private static final int TAKE_PICTURE_CODE = 100;
private Bitmap cameraBitmap = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button)findViewById(R.id.take_picture)).setOnClickListener(btnClick);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(TAKE_PICTURE_CODE == requestCode){
processCameraImage(data);
}
}
private void openCamera(){
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PICTURE_CODE);
}
private void processCameraImage(Intent intent){
setContentView(R.layout.detectlayout);
((Button)findViewById(R.id.detect_face)).setOnClickListener(btnClick);
ImageView imageView = (ImageView)findViewById(R.id.image_view);
cameraBitmap = (Bitmap)intent.getExtras().get("data");
imageView.setImageBitmap(cameraBitmap);
}
private View.OnClickListener btnClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.take_picture:
openCamera();
break;
}
}
};
}
