深入Activity的作业完成

喜闻乐见也是我最会的布局阶段

    <EditText    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_marginTop="150dp"    android:hint="@string/EditTextname"    android:textColorHint="#ff3"    android:gravity="center"    android:textColor="#ff0033"    android:id="@+id/shuru"/>

<LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content">            <Button            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="@string/button1"            style="@style/text"            android:onClick="onClick"            android:id="@+id/button1"/>            <Button            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="@string/button2"            style="@style/text"            android:id="@+id/button2"/>

</LinearLayout>        <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="@string/TextViewname"        android:gravity="center"        android:id="@+id/show"        android:textColor="#ff0033"        style="@style/text"        android:onClick="onClick"/>    </LinearLayout>

string.xml文件的实现

    <resources>    <string name="app_name">Activity</string>    <string name="button1">进入评估</string>    <string name="button2">退出</string>    <string name="EditTextname">请输入姓名</string>    <string name="TextViewname">评估结果</string>    <string name="button3">有</string>    <string name="button4">没有</string>

</resources>

styles.xml文件的实现

    <resources>

<!-- Base application theme. -->    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">        <!-- Customize your theme here. -->        <item name="colorPrimary">@color/colorPrimary</item>        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>        <item name="colorAccent">@color/colorAccent</item>    </style>    <style name="text">        <item name="android:textSize">20sp</item>    </style>

</resources>

然后再弄一个布局

    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:textColor="#ff0033"        android:id="@+id/show"/>        <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content">            <Button            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="@string/button3"            style="@style/text"            android:onClick="onClick"            android:id="@+id/button3"/>            <Button            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="@string/button4"            style="@style/text"            android:onClick="onClick"            android:id="@+id/button4"/>

</LinearLayout>

</LinearLayout>

代码实现参考如下

public class  {

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_tiaozhuan);        Intent intent = getIntent();        TextView tvshow=(TextView)findViewById(R.id.show);        EditText etshuru=(EditText)findViewById(R.id.shuru);        String name=intent.getStringExtra("name");        tvshow.setText(name);    }    public void onClick(View view){        switch (view.getId()){            case R.id.button1:            case R.id.button2:                enter();                break;        }    }

private void enter() {        EditText etshuru=(EditText)findViewById(R.id.shuru);        String name =etshuru.getText().toString();        Intent intent=new Intent(this,JiemianActivity.class);        intent.putExtra("name",name+"同学：学习Android有没有信心？");        startActivity(intent);

}}

public class  {

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.jiemian2);        Intent intent = getIntent();        TextView tvshow=(TextView)findViewById(R.id.show);        String name=intent.getStringExtra("name");        tvshow.setText(name);    }    public void onClick(View view){        switch (view.getId()){            case R.id.button3:                ruturn();                break;            case R.id.button4:                ruturn2();                break;        }    }

private void ruturn() {        Intent intent=new Intent(this,TiaozhuanActivity.class);        Button btnbutton3=(Button)findViewById(R.id.button3);        String name=btnbutton3.getText().toString();        intent.putExtra("name","评估内容返回为："+name);        startActivity(intent);    }

private void ruturn2() {        Intent intent=new Intent(this,TiaozhuanActivity.class);        Button btnbutton4=(Button)findViewById(R.id.button4);        String name=btnbutton4.getText().toString();        intent.putExtra("name","评估内容返回为："+name);        startActivity(intent);    }

}

最后的最后

作业的布局是自力更生

然而程序的实现却是一脸懵逼

参考了已有同学的代码

改造之后才有了现在的作业

发现代码的实现还有很大的问题

发现很多东西只是看的熟悉

然而根本不知道具体左右

日后的重点要弱化界面而要尽力弄懂程序的实现
