我在網上發現了這個程序,並且想要將創建新文件的部分替換爲外部存儲器,同時創建一個新文件到內部存儲器。請,如果你知道答案,你能告訴我要寫的確切代碼。我已經閱讀了這個網站上的其他問題,並最終搞亂了這個程序。謝謝。如何設置此程序使用內部存儲而不是外部(android)
佈局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/desc" />
</LinearLayout>
和Java文件
public class Main extends Activity implements OnClickListener {
private static final int TAKE_PICTURE = 0;
private Uri mUri;
private Bitmap mPhoto;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.snap)).setOnClickListener(this);
((Button) findViewById(R.id.rotate)).setOnClickListener(this);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
getContentResolver().notifyChange(mUri, null);
ContentResolver cr = getContentResolver();
try {
mPhoto = android.provider.MediaStore.Images.Media.getBitmap(cr, mUri);
((ImageView)findViewById(R.id.photo_holder)).setImageBitmap(mPhoto);
} catch (Exception e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}
}
@Override
public void onClick(View v) {
if (v.getId()== R.id.snap) {
Intent i = new Intent("android.media.action.IMAGE_CAPTURE");
File f = new File(Environment.getExternalStorageDirectory(), "photo.jpg");
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
mUri = Uri.fromFile(f);
startActivityForResult(i, TAKE_PICTURE);
} else {
if (mPhoto!=null) {
Matrix matrix = new Matrix();
matrix.postRotate(90);
mPhoto = Bitmap.createBitmap(mPhoto , 0, 0, mPhoto.getWidth(), mPhoto.getHeight(), matrix, true);
((ImageView)findViewById(R.id.photo_holder)).setImageBitmap(mPhoto);
}
}
}
}
如何從存儲文件的Android相機應用程序訪問內部存儲器? – AbhishekSaha
