Implementation of the floating dialog box and the floating dialog box

Directly run the Code:

    private void setDialog(){        View view = getLayoutInflater().inflate(R.layout.dialog_country, null);        mDialog = new Dialog(this);        mDialog.setContentView(view, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));        Window window = mDialog.getWindow();        WindowManager.LayoutParams wl = window.getAttributes();        wl.x = 0;        wl.y = getWindowManager().getDefaultDisplay().getHeight();        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;        mDialog.onWindowAttributesChanged(wl);        mDialog.setCanceledOnTouchOutside(true);        mDialog.show();                Button btnChina = (Button) view.findViewById(R.id.btnChina);        Button btnUSA = (Button) view.findViewById(R.id.btnUSA);        Button btnUK = (Button) view.findViewById(R.id.btnUK);        Button btnCancel = (Button) view.findViewById(R.id.btnCancel);                btnChina.setOnClickListener(new OnClickListener(){            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                mQuery.id(R.id.btnCountry).getTextView().setText("China");                mDialog.dismiss();            }                    });        btnUSA.setOnClickListener(new OnClickListener(){            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                mQuery.id(R.id.btnCountry).getTextView().setText("USA");                mDialog.dismiss();            }                    });        btnUK.setOnClickListener(new OnClickListener(){            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                mQuery.id(R.id.btnCountry).getTextView().setText("UK");                mDialog.dismiss();            }                    });        btnCancel.setOnClickListener(new OnClickListener(){            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                mDialog.dismiss();            }                    });    }

First, inflate an xml file to generate a view. Then, create a Dialog and set the View of the Dialog to inflate. Then, use WindowManager. layoutParams is used to set the Dialog length, width, and display position. Finally, setCanceledOnTouchOutside (true). You can click other places to exit the Dialog. The running effect is as follows:
