本文实例讲述了Android编程实现仿QQ发表说说，上传照片及弹出框效果。分享给大家供大家参考，具体如下：

代码很简单,主要就是几个动画而已,图标什么的就随便找了几个,效果图:

动画说明:

1.点击右上角按钮,菜单从顶部下拉弹出,同时背景变暗;
2.再次点击右上角按钮,点击返回键,或者点击空白区域(也就是变暗的部分),菜单向上收回;
3.点击菜单上的按钮响应事件,同时菜单收回(效果同2)

重要说明：动画结束后必须clearAnimation，否则隐藏状态的view依然能响应点击事件

主体代码:

public class MainActivity extends Activity { //添加数据按钮 private ImageView addDataIv; //下拉功能菜单 private LinearLayout dropDownView; private View bgView; //当前下拉菜单是否为显示状态 private boolean showItems = false; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); addDataIv = (ImageView) findViewById(R.id.main_newData); dropDownView = (LinearLayout) findViewById(R.id.dropDownView); bgView = findViewById(R.id.main_bg); addDataIv.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (!showItems) { showView(); } else { dismissView(); } } }); //点击空白隐藏弹出框 bgView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (showItems) { dismissView(); } } }); //下拉功能菜单上按钮的点击事件 View.OnClickListener l = new OnClickImpl(); findViewById(R.id.dropDown_item1).setOnClickListener(l); findViewById(R.id.dropDown_item2).setOnClickListener(l); findViewById(R.id.dropDown_item3).setOnClickListener(l); findViewById(R.id.dropDown_item4).setOnClickListener(l); } //显示下拉菜单 private void showView() { showItems = true; addDataIv.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.rotate_open)); dropDownView.startAnimation(AnimationUtils.loadAnimation(this, R.anim.drop_down)); dropDownView.setVisibility(View.VISIBLE); bgView.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.fade_dark)); bgView.setVisibility(View.VISIBLE); } //隐藏下拉菜单 private void dismissView() { showItems = false; addDataIv.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.rotate_close)); Animation dropUpAnim = AnimationUtils.loadAnimation(this, R.anim.drop_up); dropUpAnim.setAnimationListener(new AnimListenerImpl(dropDownView)); dropDownView.startAnimation(dropUpAnim); dropDownView.setVisibility(View.INVISIBLE); Animation fadeLightAnim = AnimationUtils.loadAnimation(MainActivity.this, R.anim.fade_light); fadeLightAnim.setAnimationListener(new AnimListenerImpl(bgView)); bgView.startAnimation(fadeLightAnim); bgView.setVisibility(View.INVISIBLE); } //点击返回键时，如果下拉菜单是显示状态，则隐藏它 @Override public void onBackPressed() { if (showItems) { dismissView(); return; } super.onBackPressed(); } private class OnClickImpl implements View.OnClickListener { @Override public void onClick(View v) { if (!showItems) { return; } int id = v.getId(); switch (id) { case R.id.dropDown_item1: Toast.makeText(MainActivity.this, "item1 onClick", Toast.LENGTH_SHORT).show(); dismissView(); break; case R.id.dropDown_item2: Toast.makeText(MainActivity.this, "item2 onClick", Toast.LENGTH_SHORT).show(); dismissView(); break; case R.id.dropDown_item3: Toast.makeText(MainActivity.this, "item3 onClick", Toast.LENGTH_SHORT).show(); dismissView(); break; case R.id.dropDown_item4: Toast.makeText(MainActivity.this, "item4 onClick", Toast.LENGTH_SHORT).show(); dismissView(); break; default: break; } } } //动画结束后必须clearAnimation，否则隐藏状态的view依然能响应点击事件 private class AnimListenerImpl implements Animation.AnimationListener { private View view; public AnimListenerImpl(View view) { this.view = view; } @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { view.clearAnimation(); } @Override public void onAnimationRepeat(Animation animation) { } }}
