课工场告诉你常用的android对话框类型实现方法
1、确定取消对话框
对话框中有2个按钮 通过调用 setPositiveButton 方法 和 setNegativeButton 方法 可以设置按钮的显示内容以及按钮的监听事件。我们使用AlerDialog 创建对话框。
builder.setIcon(R.drawable.icon);
builder.setTitle("你确定要离开吗？");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//这里添加点击确定后的逻辑
showDialog("你选择了确定");
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//这里添加点击确定后的逻辑
showDialog("你选择了取消");
}
});
builder.create().show();
2、多个按钮信息框
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setIcon(R.drawable.icon);
builder.setTitle("投票");
builder.setMessage("您认为什么样的内容能吸引您？");
builder.setPositiveButton("有趣味的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你选择了有趣味的");
}
});
builder.setNeutralButton("有思想的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你选择了有思想的");
}
});
builder.setNegativeButton("主题强的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你选择了主题强的");
}
});
builder.create().show();
3、列表框
final String[] mItems = {"item0","item1","itme2","item3","itme4","item5","item6"}; kgc.cn
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setTitle("列表选择框");
builder.setItems(mItems, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//点击后弹出窗口选择了第几项
showDialog("你选择的id为" + which + " , " + mItems[which]);
}
});
builder.create().show();
