MathView - 展示數學公式的Android視圖

依賴

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'io.github.kexanie.library:MathView:0.0.4'
}

在布局文件中定義MathView

例如:

<LinearLayout ...>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Formula one: from xml with MathJax"
        android:textStyle="bold"/>

    <io.github.kexanie.library.MathView        android:id="@+id/formula_one"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        auto:text="When \\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\)        and they are $$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$"
        auto:engine="MathJax"
        >
    </io.github.kexanie.library.MathView>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Formula two: from Java String with KaTeX"
        android:textStyle="bold"/>

    <io.github.kexanie.library.MathView        android:id="@+id/formula_two"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        auto:engine="KaTeX"
        >
    </io.github.kexanie.library.MathView>

</LinearLayout>

在Activity中獲得實例

public class MainActivity extends AppCompatActivity {
    MathView formula_two;
    String tex = "This come from string. You can insert inline formula:" +
            " \\(ax^2 + bx + c = 0\\) " +
            "or displayed formula: $$\\sum_{i=0}^n i^2 = \\frac{(n^2+n)(2n+1)}{6}$$";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    protected void onResume() {
        super.onResume();

        formula_two = (MathView) findViewById(R.id.formula_two);
        formula_two.setText(tex);
    }
}
