android 动态创建带图标的Button

用XML创建：

<Button
    android:id="@+id/btn"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:text="test button"
    android:drawableLeft="@drawable/items1"
    android:onClick="onClickBtn">
</Button>

代码创建：

LinearLayout linear = (LinearLayout) findViewById(R.id.LinearView);
Button button = new Button(this);
button.setText("test button");
button.setOnClickListener(onClickBtn);
button.setLayoutParams(
    new LayoutParams(
        android.view.ViewGroup.LayoutParams.FILL_PARENT,         
        android.view.ViewGroup.LayoutParams.WRAP_CONTENT
    )
);      

linear.addView(button);

Button添加图标：

Drawable img = getResources().getDrawable(R.drawable.items1);
img.setBounds( 0, 0, 60, 60 );
button.setCompoundDrawables(img, null, null, null);

或者：

Drawable img = getResources().getDrawable(R.drawable.items1);
button.setCompoundDrawablesWithIntrinsicBounds(img, null, null, null);

或者：

button.setCompoundDrawablesWithIntrinsicBounds(R.drawable.items1, 0, 0, 0);  

最后总结一下代码创建带图标的Button:

LinearLayout linear = (LinearLayout) findViewById(R.id.LinearView);
Button button = new Button(this);
button.setText("test button");
button.setOnClickListener(onClickBtn);
button.setLayoutParams(
    new LayoutParams(
        android.view.ViewGroup.LayoutParams.FILL_PARENT,         
        android.view.ViewGroup.LayoutParams.WRAP_CONTENT
    )
);
button.setCompoundDrawablesWithIntrinsicBounds(R.drawable.items1, 0, 0, 0);

linear.addView(button);
