**Android屏幕底部弹出DialogFragment（3）**

附录文章1，2的DialogFragment是常规的DialogFragment，但是现在的一些Android开发中，往往需要从底部弹出一个功能对话框供用户选择使用。这种底部弹出的对话框开源项目也很多，比如附录文章3，4，5,6,7,8,9,10,11。  
对Android原生的DialogFragment进行改造，也可以实现底部弹出的对话框（面板）。重点是要设置重载DialogFragment的Gravity位置：Gravity.BOTTOM。  
写一个例子：

package zhangphil.demo;
    
    import android.app.Activity;
    import android.app.Dialog;
    import android.os.Bundle;
    import android.app.DialogFragment;
    import android.app.FragmentManager;
    import android.view.Gravity;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.Window;
    import android.view.WindowManager;
    import android.widget.TextView;
    
    public class MainActivity extends Activity {
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    
    		final FragmentManager fm = this.getFragmentManager();
    
    		findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
    
    			@Override
    			public void onClick(View v) {
    				BottomDialogFragment f = new BottomDialogFragment();
    				f.show(fm, BottomDialogFragment.class.getName());
    			}
    		});
    		;
    	}
    
    	public class BottomDialogFragment extends DialogFragment {
    
    		@Override
    		public Dialog onCreateDialog(Bundle savedInstanceState) {
    
    			Dialog dialog = new Dialog(getActivity(), R.style.BottomFragmentDialog);
    
    			// 必须在setContentView之前调用。否则运行时报错。
    			dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    
    			LayoutInflater inflater = getActivity().getLayoutInflater();
    			View view = inflater.inflate(android.R.layout.simple_list_item_2, null);
    			TextView text1 = (TextView) view.findViewById(android.R.id.text1);
    			text1.setText("zhang phil");
    			TextView text2 = (TextView) view.findViewById(android.R.id.text2);
    			text2.setText("zhang phil @ csdn");
    
    			// 底部弹出的DialogFragment装载的View
    			dialog.setContentView(view);
    
    			dialog.setCancelable(true);
    			dialog.setCanceledOnTouchOutside(true);
    
    			// 设置底部弹出显示的DialogFragment窗口属性。
    			Window window = dialog.getWindow();
    			WindowManager.LayoutParams params = window.getAttributes();
    			params.gravity = Gravity.BOTTOM;
    			params.width = WindowManager.LayoutParams.MATCH_PARENT;
    			params.height = 1000; // 底部弹出的DialogFragment的高度，如果是MATCH_PARENT则铺满整个窗口
    			window.setAttributes(params);
    
    			return dialog;
    		}
    	}
    }

需要在styles.xml文件里面定义一个style：
