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:
<style name="BottomFragmentDialog" parent="@style/AppTheme"> <item name="android:layout_width">match_parent</item> <item name="android:layout_height">wrap_content</item> <item name="android:windowIsFloating">true</item> </style>
