How To Remove The Black Space Between The Title Bar And The First Element Of A Linearlayout?

I have a linearlayout, which the first element is a imageview header, and the second element is a gridview. It works fine, but I have a erroneal black space of 50px (more or less)

Solution 1:

Update: This should work just fine if you set android:theme="@android:style/Theme.NoTitleBar.Fullscreen" in the Manifest.

publicclassMainGridextendsActivity {
    private GridView myGridView;
    private ImageAdapter myImageAdapter;
    private ImageView header;

publicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LinearLayoutll=newLinearLayout(this);
    ll.setOrientation(LinearLayout.VERTICAL);
    ll.setGravity(Gravity.TOP);   // SET THIS TO TOP

    LinearLayout.LayoutParamslp=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT);
    ll.setLayoutParams(lp);
    // I'VE ADDED LAYOUTPARAMS TOO

    header = newImageView(getApplicationContext());
    header.setImageResource(R.drawable.header_acc);

    myGridView = newGridView(this);
    myImageAdapter=newImageAdapter(this);
    myGridView.setAdapter(myImageAdapter);

    ll.addView(header);
    ll.addView(myGridView);
    setContentView(ll);
}

Solution 3:

Using this in for activity tag in manifest solves your problem

android:theme="@android:style/Theme.NoTitleBar"

For Full screen you should use

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
