Android dialog自定义样式

有些时候默认的样式不能满足需求，这个时候我们可以自己写xml来布局我们的dialog代码如下，

package com.example.testdialogdemo;



import android.app.Activity;

import android.app.AlertDialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;



public class TestDialogDemoActivity extends Activity {



	private Button btn;



	@Override

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		btn = (Button) findViewById(R.id.btn);

		btn.setOnClickListener(new OnClickListener() {



			@Override

			public void onClick(View v) {

				CreateDialog();

			}

		});

	}



	private void CreateDialog() {

		AlertDialog.Builder builder = new AlertDialog.Builder(this);

		AlertDialog dialog = builder.create();

		dialog.show();

		dialog.setContentView(R.layout.update_alert_dialog_force);



		TextView update_alert_title = (TextView) dialog.findViewById(R.id.update_alert_title);

		update_alert_title.setText("升级提醒");

		TextView update_alert_content = (TextView) dialog.findViewById(R.id.update_alert_content);

		update_alert_content.setText("软件升级\n软件升级\n软件升级\n软件升级\n");

		Button update_alert_dialog_btn_ok = (Button) dialog.findViewById(R.id.update_alert_dialog_btn_ok);

		update_alert_dialog_btn_ok.setOnClickListener(new OnClickListener() {



			@Override

			public void onClick(View v) {

				Toast.makeText(getApplicationContext(), "shengji ", 1).show();

			}

		});

	}



}

xml如下，
