这是我的布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/linearlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="evip.gohybrid.com.evip.ShowBarcode">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/btnaddtoprofile"
android:text="Add to Profile"
android:textStyle="bold"
android:textSize="20dp"
android:layout_marginTop="10dp"
android:gravity="center"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/btncancel"
android:text="Cancel"
android:textStyle="bold"
android:textSize="20dp"
android:layout_below="@+id/btnaddtoprofile"
android:gravity="center"/>
这是我的代码:
Bitmap bitmap = null;
ImageView iv = new ImageView(this);
try {
bitmap = encodeAsBitmap(code, BarcodeFormat.CODE_128, 600, 300);
iv.setImageBitmap(bitmap);
} catch (WriterException e) {
e.printStackTrace();
}
relativelayout.addView(iv);
//barcode text
TextView tv = new TextView(this);
tv.setGravity(Gravity.CENTER_HORIZONTAL);
tv.setText(code);
tv.setTextSize(25);
relativelayout.addView(TV);
我想在顶部添加imageview,然后动态地添加textview,然后在我的布局文件中添加两个按钮....我怎么能这样做?任何人都可以给我建议..?

你可以这样做:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100" >
<LinearLayout
android:id="@+id/your_dinamyc_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="70"
>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="30"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/btnaddtoprofile"
android:text="Add to Profile"
android:textStyle="bold"
android:textSize="20dp"
android:layout_marginTop="10dp"
android:gravity="center"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/btncancel"
android:text="Cancel"
android:textStyle="bold"
android:textSize="20dp"
android:layout_below="@+id/btnaddtoprofile"
android:gravity="center"/>
</LinearLayout>
</LinearLayout>
我没有添加dinamycally一个imageview我添加了两个textviews而不是:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout your_dinamic_layout=(LinearLayout)findViewById(R.id.your_dinamyc_layout);
TextView tv = new TextView(this);
tv.setGravity(Gravity.CENTER_HORIZONTAL);
tv.setText("code");
tv.setTextSize(25);
your_dinamic_layout.addView(tv);
TextView tv2 = new TextView(this);
tv2.setGravity(Gravity.CENTER_HORIZONTAL);
tv2.setText("code 2");
tv2.setTextSize(30);
your_dinamic_layout.addView(tv2);
}
}
结果是:
