本周做项目时，Android自带的提示框太难看，这里做个仿IOS的提示框：

效果图：

一，创建一个自定义的布局文件(其中，像颜色，文字，最好在values文件下创建，然后引入，这里就直接创建)：

layout_dialog.xml:

二、创建一个工具类，可能经常使用，进行封装：

DialogUtil：

public class DialogUtil {

private Context mContext;

private Activity mActivity;

private OnItemClickListener mOnItemClickListener;

public DialogUtil(Activity activity, Context context){

mActivity = activity;

mContext = context;

}

/** 定义一个接口，当用户点击按钮时，可在主页面进行逻辑操作 */

public interface OnItemClickListener{

/** 取消 */

void onItemCancelClick();

/** 确定 */

void onItemConfirmClick();

}

public void setOnItemClickListener(OnItemClickListener onItemClickListener ){

this.mOnItemClickListener=onItemClickListener;

}

/** 提示框,自定义标题，内容，按钮 */

public void dialog(String title,String content, String cancelString, String confirmString){

LayoutInflater inflater = mActivity.getLayoutInflater();

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

TextView titleView = view.findViewById(R.id.vi_title);

TextView contentVIew = view.findViewById(R.id.vi_content);

TextView cancelButtonView = view.findViewById(R.id.vi_cancel_button);

TextView confirmButtonView = view.findViewById(R.id.vi_confirm_button);

titleView.setText(title);

contentVIew.setText(content);

cancelButtonView.setText(cancelString);

confirmButtonView.setText(confirmString);

AlertDialog.Builder builder = new AlertDialog.Builder(mContext);

final Dialog dialog = builder.create();

dialog.setCancelable(false);

dialog.show();

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();

/** 设置宽为屏幕的0.8大小 */

lp.width = (int) (mActivity.getWindowManager().getDefaultDisplay().getWidth() * 0.8);

dialog.getWindow().setAttributes(lp);

/** 自定义布局应该在这里添加，要在dialog.show()的后面 */

dialog.getWindow().setContentView(view);

cancelButtonView.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

mOnItemClickListener.onItemCancelClick();

dialog.dismiss();

}

});

confirmButtonView.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

mOnItemClickListener.onItemConfirmClick();

dialog.dismiss();

}

});

}

}

三、测试

private void dialog(){

DialogUtil dialogUtil = new DialogUtil(MainActivity.this,MainActivity.this);

dialogUtil.dialog("提示","欢迎使用App","取消","确定");

dialogUtil.setOnItemClickListener(new DialogUtil.OnItemClickListener(){

@Override

public void onItemCancelClick() {

Log.d("onItemClick","你点击了取消");

}

@Override

public void onItemConfirmClick() {

Log.d("onItemClick","你点击了确定");

}

});

}

/** 添加一个按钮进行测试 */

@Override

public void onClick(View v) {

switch (v.getId()){

case R.id.dialog_hint:

dialog();

break;

}

}

效果：

点击取消：

点击确定：
