我通过参考以下链接制作动画效果。 http://www.edumobile.org/android/android-development/custom-popup-window-example/comment-page-1/#comment-1649。
代码 ：
public class TutorialActivity extends Activity implements OnClickListener {
private static String TAG = TutorialActivity.class.getSimpleName();
private static final String NULL_STRING = "null";
private Button mInfoBtn;
private Animation animShow, animHide;
private AlertDialog mErrorAlertDialog;
private boolean isLogOff = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.tutorial);
mInfoBtn = (Button) findViewById(R.id.btn_info);
mInfoBtn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
initPopup();
}
/**
* Used to show the Logoff Popup menu
*/
private void initPopup() {
Intent intent = getIntent();
final PopupPanel popup = (PopupPanel) findViewById(R.id.popup_window);
popup.setVisibility(View.VISIBLE);
animShow = AnimationUtils.loadAnimation(this, R.anim.popup_show);
animHide = AnimationUtils.loadAnimation(this, R.anim.popup_hide);
popup.startAnimation(animShow);
final Button closeButton = (Button) findViewById(R.id.btnClose);
closeButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
popup.startAnimation(animHide);
popup.setVisibility(View.GONE);
}
});
final Button cancelAppointmet = (Button) findViewById(R.id.btnCancel);
final Button logoff = (Button) findViewById(R.id.btnLogoff);
logoff.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
popup.startAnimation(animHide);
popup.setVisibility(View.GONE);
}
});
cancelAppointmet.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
popup.startAnimation(animHide);
popup.setVisibility(View.GONE);
}
});
}
}
弹出面板.java
public class PopupPanel extends LinearLayout {
private Paint innerPaint, borderPaint;
public PopupPanel(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public PopupPanel(Context context) {
super(context);
init();
}
private void init() {
innerPaint = new Paint();
innerPaint.setARGB(225, 0, 0, 0);
innerPaint.setAntiAlias(true);
borderPaint = new Paint();
borderPaint.setARGB(255, 0, 0, 0);
borderPaint.setAntiAlias(true);
borderPaint.setStyle(Style.STROKE);
borderPaint.setStrokeWidth(2);
}
public void setInnerPaint(Paint innerPaint) {
this.innerPaint = innerPaint;
}
public void setBorderPaint(Paint borderPaint) {
this.borderPaint = borderPaint;
}
@Override
protected void dispatchDraw(Canvas canvas) {
RectF drawRect = new RectF();
drawRect.set(0, 0, getMeasuredWidth(), getMeasuredHeight());
canvas.drawRoundRect(drawRect, 5, 5, innerPaint);
canvas.drawRoundRect(drawRect, 5, 5, borderPaint);
super.dispatchDraw(canvas);
}
}

.Code 适用于除Samsung Galaxy S3之外的所有设备。
当我单击“信息”按钮时，我正在显示动画。
观察到在 S3 中，当我长按“信息”按钮时，动画就会出现。正常的点击事件动画不会出现。
