之前一篇文章，介绍了如何定义从屏幕底部弹出PopupWindow即《Android Animation实战之屏幕底部弹出PopupWindow》，写完之后，突然想起之前写过自定义内容显示的弹出框，就随手写了两个实例，分享出来：
第一种实现方式：继承Dialog
1.1 线定义弹出框要显示的内容：create_user_dialog.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/create_user_dialog_view" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/dialog_load_bg" android:minWidth="200dp" android:orientation="vertical" android:padding="10dp" android:paddingBottom="30dp" android:paddingTop="30dp"> <EditText android:id="@+id/text_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/edit_bg" android:hint="姓名" android:minHeight="45dp" android:textSize="18sp" /> <EditText android:id="@+id/text_mobile" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:background="@drawable/edit_bg" android:hint="手机号" android:minHeight="45dp" android:textSize="18sp" /> <EditText android:id="@+id/text_info" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:background="@drawable/edit_bg" android:gravity="top|left" android:hint="个性签名" android:minHeight="145dp" android:textSize="18sp" /> <Button android:id="@+id/btn_save_pop" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:text="保存" /> </LinearLayout>
1.2 定义要弹出的Dialog
public class CreateUserDialog extends Dialog { /** * 上下文对象 * */ Activity context; private Button btn_save; public EditText text_name; public EditText text_mobile; public EditText text_info; private View.OnClickListener mClickListener; public CreateUserDialog(Activity context) { super(context); this.context = context; } public CreateUserDialog(Activity context, int theme, View.OnClickListener clickListener) { super(context, theme); this.context = context; this.mClickListener = clickListener; } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 指定布局 this.setContentView(R.layout.create_user_dialog); text_name = (EditText) findViewById(R.id.text_name); text_mobile = (EditText) findViewById(R.id.text_mobile); text_info = (EditText) findViewById(R.id.text_info); /* * 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getWindow(),表示获得这个Activity的Window * 对象,这样这可以以同样的方式改变这个Activity的属性. */ Window dialogWindow = this.getWindow(); WindowManager m = context.getWindowManager(); Display d = m.getDefaultDisplay(); // 获取屏幕宽、高用 WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 获取对话框当前的参数值 // p.height = (int) (d.getHeight() * 0.6); // 高度设置为屏幕的0.6 p.width = (int) (d.getWidth() * 0.8); // 宽度设置为屏幕的0.8 dialogWindow.setAttributes(p); // 根据id在布局中找到控件对象 btn_save = (Button) findViewById(R.id.btn_save); // 为按钮绑定点击事件监听器 btn_save.setOnClickListener(mClickListener); this.setCancelable(true); } }
1.3 调用弹出框
public void showEditDialog(View view) { createUserDialog = new CreateUserDialog(this,R.style.loading_dialog,onClickListener); createUserDialog.show(); } private View.OnClickListener onClickListener = new View.OnClickListener() { @Override public void onClick(View v) { switch (v.getId()) { case R.id.btn_save: String name = createUserDialog.text_name.getText().toString().trim(); String mobile = createUserDialog.text_mobile.getText().toString().trim(); String info = createUserDialog.text_info.getText().toString().trim(); System.out.println(name+"——"+mobile+"——"+info); break; } } };
第二种实现方式：继承PopupWindow
2.1 定义弹出框布局文件，和1.1定义的一致
2.2 定义要弹出的PopupWindow
public class CreateUserPopWin extends PopupWindow { private Context mContext; private View view; private Button btn_save_pop; public EditText text_name; public EditText text_mobile; public EditText text_info; public CreateUserPopWin(Activity mContext, View.OnClickListener itemsOnClick) { this.mContext = mContext; this.view = LayoutInflater.from(mContext).inflate(R.layout.create_user_pop, null); text_name = (EditText) view.findViewById(R.id.text_name); text_mobile = (EditText) view.findViewById(R.id.text_mobile); text_info = (EditText) view.findViewById(R.id.text_info); btn_save_pop = (Button) view.findViewById(R.id.btn_save_pop); // 设置按钮监听 btn_save_pop.setOnClickListener(itemsOnClick); // 设置外部可点击 this.setOutsideTouchable(true); /* 设置弹出窗口特征 */ // 设置视图 this.setContentView(this.view); // 设置弹出窗体的宽和高 /* * 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getWindow(),表示获得这个Activity的Window * 对象,这样这可以以同样的方式改变这个Activity的属性. */ Window dialogWindow = mContext.getWindow(); WindowManager m = mContext.getWindowManager(); Display d = m.getDefaultDisplay(); // 获取屏幕宽、高用 WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 获取对话框当前的参数值 this.setHeight(RelativeLayout.LayoutParams.WRAP_CONTENT); this.setWidth((int) (d.getWidth() * 0.8)); // 设置弹出窗体可点击 this.setFocusable(true); } }
2.3 调用该弹框组件
public void showEditPopWin(View view) { createUserPopWin = new CreateUserPopWin(this,onClickListener); createUserPopWin.showAtLocation(findViewById(R.id.main_view), Gravity.CENTER, 0, 0); } private View.OnClickListener onClickListener = new View.OnClickListener() { @Override public void onClick(View v) { switch (v.getId()) { case R.id.btn_save_pop: String name1 = createUserPopWin.text_name.getText().toString().trim(); String mobile1 = createUserPopWin.text_mobile.getText().toString().trim(); String info1 = createUserPopWin.text_info.getText().toString().trim(); System.out.println(name1+"——"+mobile1+"——"+info1); createUserPopWin.dismiss(); break; } } };
