Android中利用LinearLayout继承实现ImageButton 转

原理：通过继承Linearlayout，摆放自己所需的imageview和textview，形成ImageButton

直接上源码：

[c-sharp] view plaincopy

import android.widget.TextView;

public class ImageButton1 extends LinearLayout

{

private ImageView mImage;

private TextView mText;

public ImageButton1(Context context, AttributeSet attrs)

{

super(context,attrs);

mImage = new ImageView(context,attrs);

mImage.setPadding(0,0,0,0);

mText = new TextView(context,attrs);

//mText.setGravity(android.view.Gravity.CENTER_HORIZONTAL);

// mText.setGravity(android.view.Gravity.CENTER_VERTICAL);

mText.setPadding(0,0,0,0);

setClickable(true);

setFocusable(true);

setBackgroundResource(android.R.drawable.btn_default);

setOrientation(LinearLayout.VERTICAL);

addView(mImage);

addView(mText);

}

}

调用自己编写的ImageButton1

[xhtml] view plaincopy

<com.test.b.ImageButton1

android:id="@+id/imbtn01"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@drawable/icon"

android:text="MOAR"

android:textColor="#ff000000"

/>

注意调用ImageButton1时，要用全名：com.test.b.ImageButton1

效果：button中上图下文字
