Android Activity实现从底部弹出或滑出选择菜单或窗口
本例使用activity实现弹出滑动窗口或菜单，主要是使用了一些设置activity的样式来实现弹出窗口和滑动效果，实现如下：[*]import android.os.Bundle;
[*]import android.view.MotionEvent;
[*]import android.view.View;
[*]import android.view.View.OnClickListener;
[*]import android.widget.Button;
[*]import android.widget.LinearLayout;
[*]import android.widget.Toast;
[*]
[*]public class SelectPicPopupWindow extends Activity implements OnClickListener{
[*]
[*] private Button btn_take_photo, btn_pick_photo, btn_cancel;
[*] private LinearLayout layout;
[*]
[*] @Override
[*] protected void onCreate(Bundle savedInstanceState) {
[*] super.onCreate(savedInstanceState);
[*] setContentView(R.layout.alert_dialog);
[*] btn_take_photo = (Button) this.findViewById(R.id.btn_take_photo);
[*] btn_pick_photo = (Button) this.findViewById(R.id.btn_pick_photo);
[*] btn_cancel = (Button) this.findViewById(R.id.btn_cancel);
[*]
[*] layout=(LinearLayout)findViewById(R.id.pop_layout);
[*]
[*] //添加选择窗口范围监听可以优先获取触点，即不再执行onTouchEvent()函数，点击其他地方时执行onTouchEvent()函数销毁Activity
[*] layout.setOnClickListener(new OnClickListener() {
[*]
[*] public void onClick(View v) {
[*] // TODO Auto-generated method stub
[*] Toast.makeText(getApplicationContext(), "提示：点击窗口外部关闭窗口！",
[*] Toast.LENGTH_SHORT).show();
[*] }
[*] });
[*] //添加按钮监听
[*] btn_cancel.setOnClickListener(this);
[*] btn_pick_photo.setOnClickListener(this);
[*] btn_take_photo.setOnClickListener(this);
[*] }
[*]
[*] //实现onTouchEvent触屏函数但点击屏幕时销毁本Activity
[*] @Override
[*] public boolean onTouchEvent(MotionEvent event){
[*] finish();
[*] return true;
[*] }
[*]
[*] public void onClick(View v) {
[*] switch (v.getId()) {
[*] case R.id.btn_take_photo:
[*] break;
[*] case R.id.btn_pick_photo:
[*] break;
[*] case R.id.btn_cancel:
[*] break;
[*] default:
[*] break;
[*] }
[*] finish();
[*] }
[*]
[*]}
