activity中代码

package com.example.dialogdemo;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class MainActivity extends Activity implements OnClickListener {    private Button button;    private MyDialog dialog;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void showDialog(View view) {        dialog = new MyDialog(this);        dialog.setContentView(R.layout.dialog);        WindowInfo windowInfo = new WindowInfo(this);        dialog.getWindow().setLayout(windowInfo.getWindowWidth(),                windowInfo.getWindowHeight() / 2);        dialog.show();        button = (Button) dialog.findViewById(R.id.button);        button.setOnClickListener(this);    }    @Override    public void onClick(View arg0) {        dialog.dismiss();    }}

activity布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="${relativePackage}.${activityClass}" >    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerInParent="true"        android:onClick="showDialog"        android:text="@string/hello_world" />RelativeLayout>

自定义dialog

package com.example.dialogdemo;import android.app.Dialog;import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.view.Gravity;import android.view.Window;public class MyDialog extends Dialog {    public MyDialog(Context context) {        super(context);        requestWindowFeature(Window.FEATURE_NO_TITLE);        Window window = getWindow();        window.setBackgroundDrawable(new ColorDrawable(0xFFFFFF));        window.setGravity(Gravity.BOTTOM);        window.setWindowAnimations(R.style.mystyle);    }}
