键盘布局文件截图如下：

android自定义密码键盘_git_02

下面看一下主界面的布局文件mian.xml

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/input"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="请输入数字"
/>
</LinearLayout>

主界面只有一个TextView控件，通过触发TextView的单击事件弹出自定义键盘

触发事件代码：

[java] view plain copy

TextView editText = (TextView)findViewById(R.id.input);
editText.setOnClickListener(new
@Override
public void
showPassWdPadView();
}
});

弹出自定义键盘方法showPassWdPadView（）

[java] view plain copy

private void
this.runOnUiThread(new
public void
// 让一个视图浮动在你的应用程序之上
WindowManager windowmanager = (WindowManager) content.getSystemService(Context.WINDOW_SERVICE);
new LayoutParams(-1, -1, WindowManager.LayoutParams.FIRST_SUB_WINDOW, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.RGBA_8888);
layoutparams.gravity = Gravity.BOTTOM;
140);
windowmanager.addView(passwdview, layoutparams);
}
});
}

这里用到了WindowManager，具体用法可参考网上。

下面是主界面的全部代码

[java] view plain copy

import
import
import
import
import
import
import
import
import
import
public class AndroidInputNumberActivity extends
private
private
private
@Override
public void
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this;
new DigitPasswordKeyPad(this);
passwdview = dpk.setup();
TextView editText = (TextView)findViewById(R.id.input);
new
@Override
public void
showPassWdPadView();
}
});
}
private void
this.runOnUiThread(new
public void
// 让一个视图浮动在你的应用程序之上
WindowManager windowmanager = (WindowManager) content.getSystemService(Context.WINDOW_SERVICE);
new LayoutParams(-1, -1, WindowManager.LayoutParams.FIRST_SUB_WINDOW, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.RGBA_8888);
layoutparams.gravity = Gravity.BOTTOM;
140);
windowmanager.addView(passwdview, layoutparams);
}
});
}
}

上面代码中passwdview这个对象就是弹出键盘界面的View实例，passwdview这个对象是在DigitPasswordKeyPad中初始化得到。

DigitPasswordKeyPad类自定义键盘类，继承自View类
