Question

如何实现全局的AlertDialog-Android开发问答

Answer 1

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.ic_new_version);
builder.setTitle("标题");		
builder.setMessage("内容");
builder.setPositiveButton("确定", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
    	
    });
builder.setCancelable(false);
AlertDialog dialog = builder.create();
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);//指定会全局,可以在后台弹出
dialog.setCanceledOnTouchOutside(false);
dialog.show();


但是要增加一个权限
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"></uses-permission>
