图像按下按钮改变大小
我意识到这个问题已经被问过多次,但我的图像在按下时会改变大小(应该是相同的大小,但图像不同)。我之前尝试过在java中设置按钮的大小,但它也不起作用。这是我的代码。
XML 选择器
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/testbuttonpressed" /> <!-- pressed -->
<item android:drawable="@drawable/testbutton" /> <!-- default -->
</selector>
XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/backtest1">
<Button
android:id="@+id/start_button"
android:layout_width="225px"
android:layout_height="55px"
android:layout_marginTop="10dp"
android:layout_gravity="center"
android:text="@string/start"
android:background="@drawable/buttonsxml"
/>
</LinearLayout>
I realize this has been asked multiple times, but my image is changing size when it is pressed (which is should be the same size, but a different image). I've previously tried setting the size of the button in java, but it didn't work either. Here is my code.
