我在 Android 中创建了相机应用程序。我创建了一项 Activity ，同一 Activity 中包含 3 个按钮和 3 个 ImageView 。当我必须单击第一个按钮时，该快照将显示在第一个 ImageView 中，然后当我单击第二个按钮时，该快照将显示在第二个 ImageView 中，与第三个按钮相同。
当我运行我的应用程序时，相机完全打开并拍摄快照，但它也无法像其他按钮一样显示在 ImageView 中。这是我的代码。
这是我的 Activity 代码
public class Take_Snap_Page extends Activity
{
ImageView imgPersonalSnap;
ImageView imgAddressProofSnap;
ImageView imgPanCardProofSnap;
ImageView imgHideBitmap;
Button btnPersonal ;
Button btnAddress;
Button btnPanCard;
Button btnSubmitSnap;
Bitmap bp;
Bitmap bitmap ;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.take_snap);
imgPersonalSnap = (ImageView)findViewById(R.id.imagesPersonnalSnap);
imgAddressProofSnap = (ImageView)findViewById(R.id.imageAddressProofSnap);
imgPanCardProofSnap = (ImageView)findViewById(R.id.imagePanCardproofSnap);
imgHideBitmap = (ImageView)findViewById(R.id.imgHide);
btnPersonal = (Button)findViewById(R.id.buttonCapture_Personal_Snap);
btnPersonal.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
imgPersonalSnap.setImageBitmap(bitmap);
}
});
btnAddress = (Button)findViewById(R.id.buttonCapture_AddressSnap);
btnAddress.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
}
});
btnPanCard = (Button)findViewById(R.id.buttonCapture_PanCardSnap);
btnPanCard.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
}
});
}
public void open() {
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0)
{
if (resultCode == RESULT_OK && data !=null )
{
// ... now let's see use the picture at data/
bp = (Bitmap) data.getExtras().get("data");
imgHideBitmap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
}
}
}
}
最佳答案
尝试使用requestCode，如下所示。
btnAddress.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(0);
}
});
btnAddress.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(1);
}
});
btnPanCard.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(2);
}
});
和
public void open(int requestCode) {
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, requestCode);
}
还有
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0)
{
if (resultCode == RESULT_OK && data !=null )
{
// ... now let's see use the picture at data/
switch(requestCode){
case 0:
bp = (Bitmap) data.getExtras().get("data");
imgPersonalSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
case 1:
bp = (Bitmap) data.getExtras().get("data");
imgAddressProofSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
case 2:
bp = (Bitmap) data.getExtras().get("data");
imgPanCardProofSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
}
}
}
}
