如何在相对布局中设置textview的边距

标签: android textview relativelayout layoutparams

我已经阅读了一些关于在父级是LinearLayout时以编程方式设置textview边距的答案,但在我的情况下,我需要在relativelayout中设置textview的边距

这是我尝试过但没有用的东西:

描述是我在以下代码中的textview:

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        params1.addRule(RelativeLayout.RIGHT_OF, idsArray[i]);
        params1.addRule(RelativeLayout.LEFT_OF, R.id.imageButtonCamera);
        params1.addRule(RelativeLayout.BELOW, R.id.divider);
        params1.setMargins(8, 8, 8, 8)

        description.setLayoutParams(params1);

任何提示?

我的布局xml文件:

带有id textViewTip的TextView是我需要更改相对和边距属性的。

答案 0 :(得分:2)

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,  RelativeLayout.LayoutParams.WRAP_CONTENT);

    params1.setMargins(8, 8, 8, 8);

    description.setLayoutParams(params1);

试试这个。因为它现在正在工作,并将提供利润。

看看我更新的ans。从xml边距布局运行良好,您可以设置xml的边距。如

   <TextView
    android:id="@+id/textViewTip"
    android:textSize="12sp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/imageViewItem"
    android:layout_alignTop="@+id/imageViewItem"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="20dp"
    android:layout_marginTop="22dp"
    android:layout_marginBottom="22dp"
    android:layout_toLeftOf="@+id/imageButtonCamera"
    android:layout_toRightOf="@+id/imageViewItem"
    android:text="Changable" />

它正常工作,如果您想以编程方式更改边距,请使用以下代码。

    LayoutParams p=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    TextView tv=(TextView)findViewById(R.id.textViewTip);

    p.setMargins(30, 30, 30, 30);
    tv.setLayoutParams(p);
