开发中android自带dialog样式有时候不能满足我们的需求,这时候就需要自定义样式了,调用dialog的setView方法可以自定义布局,代码如下
final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context); View alertDialogView = View.inflate(context, R.layout.comment_input_layout, null); final AlertDialog alertDialog = alertDialogBuilder.create(); alertDialog.setView(alertDialogView, 0, 0, 0, 0); final EditText editText = (EditText) alertDialogView.findViewById(R.id.etContent); alertDialog.show(); // 设置dialog从底部出现动画 Window window = alertDialog.getWindow(); window.setContentView(R.layout.comment_input_layout); window.setGravity(Gravity.BOTTOM); window.setWindowAnimations(R.style.comment_input_dilog_anim_style); WindowManager windowManager = ((Activity) context).getWindowManager(); Display display = windowManager.getDefaultDisplay(); WindowManager.LayoutParams lp = alertDialog.getWindow().getAttributes(); lp.width = (int) (display.getWidth()); //设置宽度 window.setAttributes(lp); });
通过window设置从底部进入动画,必须在dialog.show()后面设置
但是这样写完之后,如果布局中有edittext,当dialog显示的时候,并不会自动弹出软件盘,于是需要在show()方法之前加上如下代码:
InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(etContent, InputMethodManager.RESULT_SHOWN); imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
toggleSoftInput方法是切换软键盘的显示与隐藏,第一个参数不能传InputMethodManager.SHOW_FORCED,否则关闭dialog的时候不能关掉软键盘。
本来以为这样已经完美了。。。但是问题又来了,在声明edittext后声明了取消和确定两个button,并设置了监听,但是监听不起作用,按钮点击没有任何反应。解决办法:
在设置动画,宽度等操作后面再用window.findViewById声明控件,设置监听事件。具体原因不知道,感觉是window.setContentView(R.layout.comment_input_layout);
把原来的控件覆盖掉了,最后附上完整代码:
final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context); View alertDialogView = View.inflate(context, R.layout.comment_input_layout, null); final AlertDialog alertDialog = alertDialogBuilder.create(); alertDialog.setView(alertDialogView, 0, 0, 0, 0); final EditText editText = (EditText) alertDialogView.findViewById(R.id.etContent); //自动弹出软键盘 alertDialog.setOnShowListener(new DialogInterface.OnShowListener() { public void onShow(DialogInterface dialog) { InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(editText, InputMethodManager.RESULT_SHOWN); imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY); } }); alertDialog.show(); Window window = alertDialog.getWindow(); window.setContentView(R.layout.comment_input_layout); window.setGravity(Gravity.BOTTOM); window.setWindowAnimations(R.style.comment_input_dilog_anim_style); WindowManager windowManager = ((Activity) context).getWindowManager(); Display display = windowManager.getDefaultDisplay(); WindowManager.LayoutParams lp = alertDialog.getWindow().getAttributes(); lp.width = (int) (display.getWidth()); //设置宽度 window.setAttributes(lp); ImageButton ibtnClose=(ImageButton)window.findViewById(R.id.ibtnClose); final ImageButton ibtnRight=(ImageButton)window.findViewById(R.id.ibtnRight); final EditText etContent = (EditText) window.findViewById(R.id.etContent); ibtnClose.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { alertDialog.cancel(); } }); ibtnRight.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if(ibtnRightClickListener!=null){ ibtnRightClickListener.sendComment(etContent.getText().toString()); } alertDialog.cancel(); } });
