AlertDialog自定义关闭

摘要: AlertDialog自定义关闭、或者如何需要时关闭

如果AlertDialog里有输入框，那么如何根据自己的需要关闭AlertDialog，网上有很多是通过反射方式。这里有另外一种方法。

Builder builder = new Builder(MainActivity.this);

builder.setTitle("服务器设置");

LayoutInflater inflater = LayoutInflater.from(this);

final View view = inflater.inflate(R.layout.edit, null);

builder.setView(view);

builder.setPositiveButton(R.string.ok, new AlertDialog.OnClickListener(){

@Override

public void onClick(DialogInterface dialog, int which) {

}

});

builder.setNegativeButton(R.string.cancel, new AlertDialog.OnClickListener(){

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.dismiss();

}

});

final AlertDialog dialog = builder.create();

//builder.show();

dialog.show();

dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener()

{

@Override

public void onClick(View v)

{

Boolean wantToCloseDialog = false;

//需要时修改wantToCloseDialog的值

if(wantToCloseDialog){

dialog.dismiss();

}else{

Toast.makeText(MainActivity.this, "服务器地址不符合规范", Toast.LENGTH_SHORT).show();

}

}

});
