Android对话框

一：最简单的对话框

AlertDialog dialog = new AlertDialog.Builder(this)
.setIcon(R.mipmap.icon)//设置标题的图片
.setTitle(“我是对话框”)//设置对话框的标题
.setMessage(“我是对话框的内容”)//设置对话框的内容
//设置对话框的按钮
.setNegativeButton(“取消”, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, “点击了取消按钮”, Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
})
.setPositiveButton(“确定”, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, “点击了确定的按钮”, Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
}).create();
dialog.show();

二：列表对话框

 final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
        AlertDialog dialog = new AlertDialog.Builder(this)
                .setIcon(R.mipmap.icon)//设置标题的图片
                .setTitle("列表对话框")//设置对话框的标题
                .setItems(items, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(MainActivity.this, items[which], Toast.LENGTH_SHORT).show();
                    }
                })
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                }).create();
        dialog.show();

三：单选列表对话框

final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
        AlertDialog dialog = new AlertDialog.Builder(this)
                .setIcon(R.mipmap.icon)//设置标题的图片
                .setTitle("单选列表对话框")//设置对话框的标题
                .setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(MainActivity.this, items[which], Toast.LENGTH_SHORT).show();
                    }
                })
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                }).create();
        dialog.show();

四：复选列表对话框

final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
        final boolean checkedItems[] = {true, false, true, false};
        AlertDialog dialog = new AlertDialog.Builder(this)
                .setIcon(R.mipmap.icon)//设置标题的图片
                .setTitle("多选对话框")//设置对话框的标题
                .setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                        checkedItems[which] = isChecked;
                    }
                })
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        for (int i = 0; i < checkedItems.length; i++) {
                            if (checkedItems[i]) {
                                Toast.makeText(MainActivity.this, "选中了" + i, Toast.LENGTH_SHORT).show();
                            }
                        }
                        dialog.dismiss();
