android自定义dialog对话框,android的自定义dialog对话框实现
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
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;
}
@Override
protected 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
