Android 普通提示弹窗和带输入框弹窗简单实现

在布局页面添加一个fab按钮（fab_user_Add），可以简单的Button按钮就可以

   <cc.trity.floatingactionbutton.FloatingActionButton
            android:id="@+id/fab_user_add"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:layout_gravity="right"
            android:layout_marginRight="2dp"
            android:src="@drawable/ic_add"
            android:backgroundTint="#4b98fb"
            app:rippleColor="#9CC4F7"
            app:borderWidth="0dp"
            android:clickable="true"
            android:layout_marginBottom="20dp" />

在Activity调用方法

1）普通提示弹窗

 FloatingActionButton fabUserAdd = findViewById(R.id.fab_user_add);
        fabUserAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDialog.Builder builder = new AlertDialog.Builder(CollectActivity.this);
                builder.setTitle("删除提醒")
                        .setIcon(android.R.drawable.ic_dialog_info)
                         .setMessage("您是否确定删除数据？")
                        .setNegativeButton("否", null);
                builder.setPositiveButton("是", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {

                        Log.i("测试","点击删除");
                    }
                });
                builder.show();
            }
        });

2）带输入框弹窗

   FloatingActionButton fabUserAdd = findViewById(R.id.fab_user_add);
        fabUserAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                final EditText inputServer = new EditText(CollectActivity.this);
                AlertDialog.Builder builder = new AlertDialog.Builder(CollectActivity.this);
                builder.setTitle("用户验证")
                        .setIcon(android.R.drawable.ic_dialog_info)
                        .setView(inputServer)
                        .setNegativeButton("取消", null);
                builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        inputServer.getText().toString();
                        Log.i("测试","输入用户："+ inputServer.getText());
                    }
                });
                builder.show();

            }
        });
