二主代码编写

此处将逻辑抽取到方法里，在需要的地方调用即可：

/** *对话框使用逻辑 */ protected void showQQDialog() { //加载对话框布局 View view = getLayoutInflater().inflate(R.layout.dialog_qq_item, null); final Dialog dialog = new Dialog(this); dialog.setContentView(view, new ViewGroup.LayoutParams( ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Window window = dialog.getWindow();//获取窗口 window.setWindowAnimations(R.style.style_anim_dialog); // 设置显示动画 //设置对话框背景为透明 <color name="trans">#00000000</color> window.setBackgroundDrawableResource(R.color.trans); WindowManager.LayoutParams wl = window.getAttributes(); wl.y = getWindowManager().getDefaultDisplay().getHeight(); // 以下这两句是为了保证按钮可以水平满屏 wl.width = Toolbar.LayoutParams.MATCH_PARENT; wl.height = Toolbar.LayoutParams.WRAP_CONTENT; dialog.onWindowAttributesChanged(wl); // 设置显示位置 dialog.setCanceledOnTouchOutside(true); // 设置点击外围解散 dialog.show();//展示对话框 view.findViewById(R.id.but_cancel).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); view.findViewById(R.id.but_open_photo).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType("image/*"); startActivity(intent); //打开系统图库 } }); view.findViewById(R.id.but_take_photo).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivity(intent);// 打开系统拍照 } }); }本项目源码地址：https://github.com/toly1994328/DialogTest
