第一种方法，只是单纯的实现一个自定义TextView：
public class MyView extends View {
private String text;
private int color;
private float textsize;
public MyView(Context context) {
super(context);
init(null);
}
public MyView(Context context, @Nullable AttributeSet attrs){
super(context,attrs);
init(attrs);
}
private void init(@Nullable AttributeSet attrs) {
TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.MyView);
text = typedArray.getString(R.styleable.MyView_text);
color = typedArray.getColor(R.styleable.MyView_textcolor, 0xffffff);
textsize = typedArray.getDimension(R.styleable.MyView_textsize, 16);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setColor(color);
paint.setTextSize(textsize);
canvas.drawText(text,300,300,paint);
}
}
在values中创建一个attrs
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="MyView">
<attr name="text" format="string"></attr>
<attr name="textsize" format="dimension"></attr>
<attr name="textcolor" format="color"></attr>
</declare-styleable>
</resources> 布局文件：<View.MyView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
app:text="申文静"
app:textcolor="#000000"
app:textsize="16sp"
/>第二种方法继承一个linerlayout,inflate一个布局进去public class MyTextView extends LinearLayout {
private TextView biaoti;
private ImageView img;
public MyTextView(Context context) {
super(context);
}
public MyTextView(Context context, @Nullable AttributeSet attrs){
super(context,attrs);
init(context);
}
private void init(Context context) {
inflate(context, R.layout.second,this);
biaoti = (TextView) findViewById(R.id.biaoti);
img = (ImageView) findViewById(R.id.img);
img.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getContext(),"我在自定义view中被点击了",Toast.LENGTH_SHORT).show();
}
});
}
}
布局文件;<View.MyTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true">
</View.MyTextView><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<TextView
android:id="@+id/biaoti"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="申文静"
android:textSize="20sp"
/>
<ImageView
android:id="@+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@mipmap/ic_launcher"/>
</LinearLayout>
