[b]使用 Button 时为了让用户有“按下”的效果,有两种实现方式: [/b]
[b][b] 1.JAVA代码实现: [/b] [/b]
imageButton.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
//更改为按下时的背景图片
v.setBackgroundResource(R.drawable.pressed);
}else if(event.getAction() == MotionEvent.ACTION_UP){
//改为抬起时的图片
v.setBackgroundResource(R.drawable.released);
}
return false;
}
});
[b] 2.XML实现:
[/b]
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android
">
<item android:state_pressed="false" android:drawable="@drawable/button_add" />
<item android:state_pressed="true" android:drawable="@drawable/button_add_pressed" />
<item android:state_focused="true" android:drawable="@drawable/button_add_pressed" />
<item android:drawable="@drawable/button_add" />
</selector>
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android
">
<item android:state_pressed="false" android:drawable="@drawable/button_add" />
<item android:state_pressed="true" android:drawable="@drawable/button_add_pressed" />
<item android:state_focused="true" android:drawable="@drawable/button_add_pressed" />
<item android:drawable="@drawable/button_add" />
</selector>
[b]这个文件放在
drawable
目录下面。命名为
button_add_x.xml,使用方法如下:
[/b]
[b]<ImageButton
android:id="@+id/ImageButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:src="@drawable/button_add_x" >
</ImageButton>
<ImageButton
android:id="@+id/ImageButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:src="@drawable/button_add_x" >
</ImageButton>
[/b]
[b] 3.采用Drawable的颜色过滤:
[/b]
[b]/**
* 按下这个按钮进行的颜色过滤
*/
public final static float[] BT_SELECTED=new float[] {
2, 0, 0, 0, 2,
0, 2, 0, 0, 2,
0, 0, 2, 0, 2,
0, 0, 0, 1, 0 };
/**
* 按钮恢复原状的颜色过滤
*/
public final static float[] BT_NOT_SELECTED=new float[] {
1, 0, 0, 0, 0,
0, 1, 0, 0, 0,
0, 0, 1, 0, 0,
0, 0, 0, 1, 0 };
/**
* 按钮焦点改变
*/
public final static OnFocusChangeListener buttonOnFocusChangeListener=new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
else
{
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_NOT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
}
};
/**
* 按钮触碰按下效果
*/
public final static OnTouchListener buttonOnTouchListener=new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
else if(event.getAction() == MotionEvent.ACTION_UP){
v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_NOT_SELECTED));
v.setBackgroundDrawable(v.getBackground());
}
return false;
}
};
/**
* 设置图片按钮获取焦点改变状态
* @param inImageButton
*/
public final static void setButtonFocusChanged(View inView)
{
inView.setOnTouchListener(buttonOnTouchListener);
inView.setOnFocusChangeListener(buttonOnFocusChangeListener);
}
