标签: android mobile

我是移动开发的新手,我正在尝试运行我的活动,并使用我的手机/模拟器查看我的布局结果。 在设计模式下,它看起来不错,但是当我在模拟器/手机上运行时,所有元素都是一个在另一个上面的。

我有这些文件:

activity_item_page.xml

ItemPageActivity.java

import android.view.View;
import android.widget.HorizontalScrollView;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class ItemPageActivity extends AppCompatActivity {
    private LinearLayout mGallery;
    private int[] mImgIds;
    private LayoutInflater mInflater;
    private HorizontalScrollView horizontalScrollView;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_item_page);
        mInflater = LayoutInflater.from(this);
        initData();
        initView();
    }

    private void initData()
    {
        mImgIds = new int[] { R.drawable.ic_1, R.drawable.ic_2, R.drawable.ic_3,R.drawable.ic_4
        };
    }

    private void initView()
    {
        mGallery = (LinearLayout) findViewById(R.id.id_gallery);

        for (int i = 0; i < mImgIds.length; i++)
        {

            View view = mInflater.inflate(R.layout.activity_gallery_item,
                    mGallery, false);
            ImageView img = (ImageView) view
                    .findViewById(R.id.id_index_gallery_item_image);
            img.setImageResource(mImgIds[i]);
            TextView txt = (TextView) view
                    .findViewById(R.id.id_index_gallery_item_text);
            txt.setText("info "+i);
            mGallery.addView(view);
        }
    }
}

我还附加了设计和模拟器的图像。 enter image description here enter image description here
