下面介绍两种弹出方式,一种是利用TranslateAnimation动画,另一种是PopupWindow
左边是动画,右边是popupwindow。
第一种方式:
public class MainActivity extends AppCompatActivity {
private LinearLayout mPopupLayout;
private Button btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mPopupLayout = (LinearLayout) findViewById(R.id.start_ctrl);
btn = findViewById(R.id.start_btn);
startAnim();
}
private void startAnim() {
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//设置动画,从自身位置的最下端向上滑动了自身的高度,持续时间为500ms
final TranslateAnimation ctrlAnimation = new TranslateAnimation(
TranslateAnimation.RELATIVE_TO_SELF, 0, TranslateAnimation.RELATIVE_TO_SELF, 0,
TranslateAnimation.RELATIVE_TO_SELF, 1, TranslateAnimation.RELATIVE_TO_SELF, 0);
ctrlAnimation.setDuration(400l); //设置动画的过渡时间
mPopupLayout.postDelayed(new Runnable() {
@Override
public void run() {
mPopupLayout.setVisibility(View.VISIBLE);
mPopupLayout.startAnimation(ctrlAnimation);
}
}, 500);
}
});
}
}

第二种方式:
先创建一个popupwindow:
private PopupWindow mPopupWindow;
mPopupWindow = createPopupWindow(contentView);
将需要的布局文件传入即可:
private PopupWindow createPopupWindow(View contentView) {
contentView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
PopupWindow popupWindow = new PopupWindow(contentView, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT, true);
popupWindow.setTouchable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.setFocusable(true);
popupWindow.setAnimationStyle(R.style.PopupAnimation);
popupWindow.setClippingEnabled(true);
popupWindow.setSoftInputMode(PopupWindow.INPUT_METHOD_NEEDED);
popupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
popupWindow.showAtLocation(mRootLayout, Gravity.NO_GRAVITY, 0, DimenUtils.getWindowHeight() - contentView.getMeasuredHeight());
popupWindow.update();
popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
@Override
public void onDismiss() {
setWindowBackgroundAlpha(1.0f);//当PopupWindow消失的时候Window完全透明
}
});
return popupWindow;
}
