我想重新设置TextView的高度后,我已经把它添加到在XML文件中的主窗口。
I want to reset a textView height after I have added it to the main window in the xml file.
里面RelativeLayout的,
inside a RelativeLayout,
<TextView
android:id="@+id/text_l"
android:layout_width="50sp"
android:layout_height="50sp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginLeft="10sp"
android:layout_marginTop="145dp"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#000000" >
</TextView>
我只是想将其从50改为70:
I just want to change it from 50 to 70:
我想:
TextView text = (TextView)findViewById(R.id.text_l);
text.setHeight(70);
但没有任何改变。
but nothing changed.
推荐答案
您应该通过的LayoutParams
更改
LayoutParams params = textView.getLayoutParams();
params.height = 70;
textView.setLayoutParams(params);
修改
您不应使用尺寸以像素为单位在您code,使用尺寸是:
You should not use sizes in pixels in you code, use dimensions for this:
dimens.xml:
dimens.xml:
<dimen name="text_view_height">50dp</dimen>
在code:
params.height = getResources().getDimensionPixelSize(R.dimen.text_view_height);
