Android自定义dialog对话框

一：自定义dialog 如何填充布局

①自定MyDialog类，在类里关联布局

<span style="white-space:pre"></span><pre name="code" class="java">public class MyDialog extends AlertDialog { Context context;public MyDialog(Context context) {    super(context);    this.context = context;}public MyDialog(Context context, int theme){    super(context, theme);    this.context = context;}@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    this.setContentView(R.layout.layout_dialog);}}

然后，再在外面类MainActivity引用这个自定义类

  Dialog dialog = new MyDialog(ActivityB.this,R.style.MyDialog);dialog.show();

②在代码里填充布局

//在MainActivity类里直接填充

         AlertDialog.Builder b = new AlertDialog.Builder(MainActivity.this);           AlertDialog dialog1 = b.create();           LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);             View view = inflater.inflate(R.layout.layout_dialog, null);             dialog1.setView(view, 0, 0, 0, 0);            dialog1.show();

二：自定义dialog 的按钮的事件

系统的dialog ，在给对话框上的button设置事件的时候可以通过setPositiveButton（）、setNegativeButton（）这两个方法来实现。但是自定义的dialog就不能再用这两个方法了，可以换成setOnClickListener（）方法。//setOnClickListener(android.view.View.OnClickListener object);

 protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_b); btn_ctrl = (Button) findViewById(R.id.btn_ctrl); tv_ticket = (TextView)findViewById(R.id.tv_ticket);    btn_ctrl.setOnClickListener(new OnClickListener() {           @Override           public void onClick(View v) {                         //初始化一个自定义的Dialog                Dialog dialog = new MyDialog(ActivityB.this,R.style.MyDialog); dialog.show();                   }  });  tv_ticket.setOnClickListener(new OnClickListener() { @Override  public void onClick(View v) {      AlertDialog.Builder dialog1 = new AlertDialog.Builder(ActivityB.this);                       dialog1.getWindow().setLayout(450, 330);               LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);                 View view = inflater.inflate(R.layout.dialog_reconn, null);                  dialog1.setView(view);                dialog1.show();          }});        }

点完按钮之后，默认对话框不隐藏，调用dialog.dismiss()方法就可以隐藏对话框
