自定义alertDialog

1.代码中

   

public void onClick(View v) {
      switch (v.getId()){

                                

 case R.id.iv_pic:
                 

case R.id.recipe_up://上传食谱
    alertDialog = new AlertDialog.Builder(this).create();
    //显示对话框
    alertDialog.show();
    View view = LayoutInflater.from(this).inflate(R.layout.dialog_pic_info,null);
    alertDialog.setContentView(view);
    //给Dialog中的子view设置事件监听
    view.findViewById(R.id.dialog_takepic).setOnClickListener(this);//拍照
    view.findViewById(R.id.dialog_pic).setOnClickListener(this);//本地照片
    view.findViewById(R.id.dialog_native).setOnClickListener(this);//取消
    alertDialog.setContentView(view);
    //show之前设置返回键无效，触摸屏无效
    alertDialog.setCancelable(false);
    break;
case R.id.dialog_takepic://拍照
    alertDialog.dismiss();

    break;
case R.id.dialog_pic://本地上传
    alertDialog.dismiss();
    //这里实现业务逻辑
    
    break;
case R.id.dialog_native://取消
    alertDialog.dismiss();
    break;

}2.布局文件

<LinearLayout
     android:layout_width="420dp"
     android:layout_height="wrap_content"
     android:orientation="vertical"
     android:background="@drawable/corners_bg">
 <TextView
     android:padding="12dp"
     android:textSize="15dp"
     android:gravity="center_horizontal"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:text="拍照"/>
     <View
         android:layout_width="match_parent"
         android:layout_height="1dp"
         android:background="#f7f7f7"/>
 <TextView
     android:padding="12dp"
     android:textSize="15dp"
     android:gravity="center_horizontal"
